  • Title: Acknowledging Yade — Yade 2014-08-13.git-b94eb65 documentation
    Descriptive info: previous.. In order to let users cite Yade consistently in publications, we provide a list of bibliographic references for the different parts of the documentation, as in the citation model pushed by.. CGAL.. This way of acknowledging Yade is also a way to make developments and documentation of Yade more attractive for researchers, who are evaluated on the basis of citations of their work by others.. We therefore kindly ask users to cite Yade as accurately as possible in their papers.. A more detailed discussion of the citation model and its application to Yade can be found.. here.. If new developments are presented and explained in self-contained papers (at the end of a PhD, typically), we will be glad to include them in the documentation and to reference them in the list below.. Any other substantial improvement is welcome and can be discussed in the.. yade-dev.. mailing list.. If it is not possible to choose the right chapter (but please try), you may  ...   collection with the three volumes (or chapters ) listed below, also provided as.. bibtex entries.. Please cite the chapter that is the most relevant in your case.. For instance, a paper using one of the documented contact laws will cite the reference documentation.. [yade:reference].. ; if programing concepts are discussed, Yade s manual.. [yade:manual].. will be cited; the theoretical background.. [yade:background].. can be used as the refence for contact detection, time-step determination, or periodic boundary conditions.. The reference documentation includes details on equations and algorithms found at the highest levels of Yade (contact laws, boundary conditions controllers, pre- and post-processing modules,.. ).. (pdf version).. :.. Thoeni, “Yade Reference Documentation,” in Yade Documentation (V.. Software design, user s and programmer s manuals are in.. Šmilauer, A.. Modenese, and J.. Stránský, “Yade Using and Programming,” in Yade Documentation (V.. Fundamentals of the DEM as implemented in Yade are explained in.. Šmilauer and B..

  • Title: Introduction — Yade 2014-08-13.git-b94eb65 documentation
    Descriptive info: Before you start moving around in Yade, you should have some prior knowledge.. Basics of command line in your Linux system are necessary for running yade.. Look on the web for tutorials.. Python language; we recommend the official.. Python tutorial.. Reading further documents on the topis, such as.. Dive into Python.. will certainly not hurt either.. You are advised to try all commands described yourself.. Don t be afraid to experiment.. Starting yade.. Yade is being run primarily from terminal; the name of command is.. (In case you did not install from package, you might need to give specific path to the command.. ):.. $ yade Welcome to Yade TCP python prompt on localhost:9001, auth cookie `sdksuy TCP info provider on localhost:21000 [[ ^L clears screen, ^U kills line.. F12 controller, F11 3d view, F10 both, F9 generator, F8 plot.. ]] Yade [1]:.. These initial lines give you some information about.. some information for.. Remote control.. , which you are unlikely to need now;.. basic help for the command-line that just appeared (.. [1]:.. ).. Type.. quit().. exit().. or simply press.. ^D.. to quit Yade.. The command-line is.. ipython.. , python shell with enhanced interactive capabilities; it features persistent history (remembers commands from your last sessions), searching and so on.. See ipython s documentation for more details.. Typically, you will not type Yade commands by hand, but use.. scripts.. , python programs describing and running your simulations.. Let us take the most simple script that will just print Hello world! :.. print.. Hello world!.. Saving such script as.. hello.. py.. , it can be given as argument to yade:.. $ yade hello.. py Welcome to Yade TCP python prompt on localhost:9001, auth cookie `askcsu TCP info provider on localhost:21000 Running script hello.. py ## the script is being run Hello world! ## output from the script [[ ^L clears screen, ^U kills line.. Yade will run the script and then drop to the command-line again.. [3].. If you want Yade to quit immediately after running the script, use the.. -x.. switch:.. $ yade -x script.. There is more command-line options than just.. , run.. -h.. to see all of them.. Options:.. --version.. show program s version number and exit.. --help.. show this help message and exit.. -j.. THREADS.. --threads=.. Number of OpenMP threads to run; defaults to 1.. Equivalent to setting OMP_NUM_THREADS environment variable.. --cores=.. CORES.. Set number of OpenMP threads (as threads) and in addition set affinity of threads to the cores given.. --update.. Update deprecated class names in given script(s) using text search replace.. Changed files will be backed up with ~ suffix.. Exit when done without running any simulation.. --nice=.. NICE.. Increase nice level (i.. e.. decrease priority) by given number.. Exit when the script finishes.. -n.. Run without graphical interface (equivalent to unsetting the DISPLAY environment variable).. --test.. Run regression test suite and exit; the exists status is 0 if all tests pass, 1 if a test fails and 2 for an unspecified exception.. --check.. Run a series of user-defined check tests as described in /build/buildd/yade- daily-1+3021+27~lucid1/scripts/test/checks/README.. --performance.. Starts a test to measure the productivity.. --no-gdb.. Do not show backtrace when yade crashes (only effective with debug).. Footnotes.. The executable name can carry a suffix, such as version number (.. yade-0.. 20.. ), depending on compilation options.. Packaged versions on Debian systems always provide the plain.. alias, by default pointing to latest stable version (or latest snapshot, if no stable version is installed).. You can use.. update-alternatives.. to change this.. In general, Unix.. shell.. (command line) has environment variable.. PATH.. defined, which determines directories searched for executable files if you give name of the file without path.. Typically, $PATH contains.. /usr/bin/.. /usr/local/bin.. /bin.. and others; you can inspect your.. by typing.. echo.. $PATH.. in the shell (directories are separated by.. If Yade executable is not in directory contained in.. , you have to specify it by hand, i.. by typing the path in front of the filename, such as in.. /home/user/bin/yade.. and similar.. You can also navigate to the directory itself (.. cd.. ~/bin/yade.. , where.. ~.. is replaced by your home directory automatically) and type.. /yade.. then (the.. is the current directory, so.. /.. specifies that the file is to be found in the current directory).. To save typing, you can add the directory where Yade is installed to your.. , typically by editing.. ~/.. profile.. (in normal cases automatically executed when shell starts up) file adding line like.. export.. PATH=/home/user/bin:$PATH.. You can also define an.. alias.. by saying.. yade= /home/users/bin/yade.. in that file.. Details depend on what shell you use (bash, zsh, tcsh, …) and you will find more information in introductory material on Linux/Unix.. Plain Python interpreter exits once it finishes running the script.. The reason why Yade does the contrary is that most of the time script only sets up simulation and lets it run; since computation typically runs in background thread, the script is technically finished, but the computation is running.. Creating simulation.. To create simulation, one can either use a specialized class of type.. FileGenerator.. to create full scene, possibly receiving some parameters.. Generators are written in c++ and their role is limited to well-defined scenarios.. For instance, to create triaxial test scene:.. Yade [1]:.. TriaxialTest.. (.. numberOfGrains.. =.. 200.. load.. ().. ---------------------------------------------------------------------------.. NameError Traceback (most recent call last).. /home/buildbot/yade/yade-full/install/lib/x86_64-linux-gnu/yade-buildbot/py/yade/__init__.. pyc in module ().. NameError: name yade is not defined.. Yade [2]:.. len.. bodies.. Out.. ]:.. 0.. Generators are regular yade objects that support attribute access.. It is also possible to construct the scene by a python script; this gives much more flexibility and speed of development and is the recommended way to create simulation.. Yade provides modules for streamlined body construction, import of geometries from files and reuse of common code.. Since this topic is more involved, it is explained in the.. Running simulation.. As explained above, the loop consists in running defined sequence of engines.. Step number can be queried by.. iter.. and advancing by one step is done by.. step()..

Normal simulations, however, are run continuously.. Starting/stopping the loop is done by.. run().. pause().. ; note that.. returns control to Python and the simulation runs in background; if you want to wait for it finish, use.. wait()..

Yade [35]:.. bodies.. append(s).. IndexError: Body already has id 0 set; appending such body (for the second time) is not allowed.. Bodies can be iterated over using standard python iteration syntax:.. Yade [36]:.. for.. in.. :.. id.. 0 1.. 1 0.. are always between pair of bodies; usually, they are created by the collider based on spatial proximity; they can, however, be created explicitly and exist independently of distance.. Each interaction has 2 components:.. IGeom.. holding geometrical configuration of the two particles in collision; it is updated automatically as the particles in question move and can be queried for various geometrical characteristics, such as penetration distance or shear strain.. Based on combination of types of.. Shapes.. of the particles, there might be different storage requirements; for that reason, a number of derived classes exists, e.. for representing geometry of contact between.. Sphere+Sphere.. Cylinder+Sphere.. etc.. Note, however, that it is possible to represent many type of contacts with the basic sphere-sphere geometry (for instance in.. Ig2_Wall_Sphere_ScGeom.. IPhys.. representing non-geometrical features of the interaction; some are computed from..

NameError: name Vector3 is not defined.. Yade [46]:.. 46.. You will only rarely modify forces from Python; it is usually done in c++ code and relevant documentation can be found in the Programmer s manual.. Function components.. In a typical DEM simulation, the following sequence is run repeatedly:.. reset forces on bodies from previous step.. approximate collision detection (pass 1).. detect exact collisions of bodies, update interactions as necessary.. solve interactions, applying forces on bodies.. apply other external conditions (gravity, for instance).. change position of bodies based on forces, by integrating motion equations.. Typical simulation loop; each step begins at body-centered bit at 11 o clock, continues with interaction bit, force application bit, miscillanea and ends with time update.. Each of these actions is represented by an.. Engine.. , functional element of simulation.. The sequence of engines is called.. simulation loop.. Engines.. Simulation loop, shown at img.. img-yade-iter-loop.. , can be described as follows in Python (details will be explained later); each of the.. engine.. items is instance of a type deriving from.. # reset forces.. ForceResetter.. (),.. # approximate collision detection, create interactions.. InsertionSortCollider.. Bo1_Sphere_Aabb.. Bo1_Facet_Aabb.. ()]),.. # handle interactions.. InteractionLoop..

GravityEngine.. gravity.. -.. 9.. 81.. )),.. # update positions using Newton s equations.. NewtonIntegrator.. There are 3 fundamental types of Engines:.. GlobalEngines.. operating on the whole simulation (e.. looping over all bodies and applying force based on their mass).. PartialEngine.. operating only on some pre-selected bodies (e.. ForceEngine.. applying constant force to some bodies).. Dispatchers.. do not perform any computation themselves; they merely call other functions, represented by function objects,.. Functors.. Each functor is specialized, able to handle certain object types, and will be dispatched if such obejct is treated by the dispatcher.. Dispatchers and functors.. For approximate collision detection (pass 1), we want to compute.. bounds.. for all.. in the simulation; suppose we want bound of type.. axis-aligned bounding box.. Since the exact algorithm is different depending on particular.. , we need to provide functors for handling all specific cases.. The line:.. ()]).. creates.. (it internally uses.. BoundDispatcher.. , but that is a detail).. It traverses all bodies and will, based on.. type of each.. body.. , dispatch one of the functors to create/update.. for that particular body.. In the case shown, it has 2 functors, one handling.. spheres.. , another.. facets.. The name is composed from several parts:.. Bo.. (functor creating.. ), which accepts.. type.. and creates an.. (axis-aligned bounding box; it is derived from.. objects are used by.. All.. Bo1.. functors derive from.. BoundFunctor.. The next part, reading.. hides 3 internal dispatchers within the.. engine; they all operate on interactions and are, for performance reasons, put together:.. IGeomDispatcher.. uses the first set of functors (.. Ig2.. ), which are dispatched based on combination of.. objects.. Dispatched functor resolves exact collision configuration and creates.. (whence.. Ig.. in the name) associated with the interaction, if there is collision.. The functor might as well fail on approximate interactions, indicating there is no real contact between the bodies, even if they did overlap in the approximate collision detection.. The first functor,.. , is called on interaction of 2.. Spheres.. and creates.. instance, if appropriate.. The second functor,.. , is called for interaction of.. with.. and might create (again) a.. IGeomFunctor.. (they are documented at the same place).. IPhysDispatcher.. dispatches to the second set of functors based on combination of.. ; these functors return return.. instance (the.. Ip.. prefix).. In our case, there is only 1 functor used,.. , which create.. from 2.. FrictMat s.. Ip2.. functors are derived from.. IPhysFunctor.. LawDispatcher.. dispatches to the third set of functors, based on combinations of.. (wherefore.. in their name again) of each particular interaction, created by preceding functors.. Law2.. functors represent constitutive law ; they resolve the interaction by computing forces on the interacting bodies (repulsion, attraction, shear forces, …) or otherwise update interaction state variables.. functors all inherit from.. LawFunctor.. There is chain of types produced by earlier functors and accepted by later ones; the user is responsible to satisfy type requirement (see img.. img-dispatch-loop.. An exception (with explanation) is raised in the contrary case.. Chain of functors producing and accepting certain types.. In the case shown, the.. functors produce.. ScfGeom.. instances from all handled.. combinations; the.. functor produces.. The constitutive law functor.. accepts the combination of types produced.. Note that the types are stated in the functor s class names.. When Yade starts, O.. engines is filled with a reasonable default list, so that it is not strictly necessary to redefine it when trying simple things.. The default scene will handle spheres, boxes, and facets with.. frictional.. properties correctly, and adjusts the timestep dynamically.. You can find an example in simple-scene-default-engines..
