  • Change in the calculation of the normal and tangential stiffness and damping. The change affects only the behavior when one of the two parameters is zero, e.g. for two particles with different stiffness k1 and k2, the contact stiffness will always be k = k1*k2/(k1+k2). Before it gave the same except when k2 = 0 (respectively k1 = 0), where it gave k = k1 (resp. k=k2). This is done to ensure continuity in the behavior when one of the two parameter tend to zero. Add a function contactParameterCalculation in Ip2_ViscElMat_ViscElMat_ViscElPhys to avoid code duplication.

  • enable setting FlowEngine by number of steps or by deformation aplitude
  • a fix in bibtex
  • remove excess verbosity
  • add thread number attribute to change the number of thread of interactionLoop dynamicaly during simulations. Also usefull combined with parallel engine (for fine grain tuning of thread number in each subprocess)
  • 1. Add thread number to parallel engine, can be changed dynamicaly. Uncouples the number of threads in parallel engines and in slaves. 2. Enable nested parallel regions (disabled on many systems by default) else the parallel engine is doing no good
  • 1. Replace one loop on cells by an optimized vector iterator 2. Clean an horrible block of code (not only ugly, it was also slow)
  • introduce a position buffer for faster updates of volumes
  • Use retriangulation conditions more consistently. The solvers are not swapped before a given fraction of the permutation interval now, to reduce overheads.
  • small change in the initialization logic, now defining the two position buffers if "first"
  • make ompThread an attribute of Engine, as it likely to be used more and more in the future. It is then inherited by InteractionLoop and ParallelEngine

  • Fix the F9-F12 keys binding for IPython>=0.12
  • add the correct prefactor in normal lubrication relation -overlap the two triangulations during one iteration in order to have the "previous" forces defined in the normal lubrication equation
  • Update the documentation of the ompThreads attribute.
  • fix again the offset of ids in SpherePack.toSimulation (previous fix was assuming two bodies per clump)
  • fix https://bugs.launchpad.net/yade/+bug/923929 again, as shown by François it could still happen in some cases (see example in the bug report)
  • remove the check/throw when generating aperiodic 2D packings, since the algorithm actually support that.
  • Define O.engine with a default list at startup, with example script and notes in the documentation.
  • remove utils prefix
  • Updates and improvements in the triax-tutorial material - smallfix in a note in introduction.rst

  • improved version of TriaxialStressController, controling not onlt stress but also strain rate - making the interface more similar (but still not exactly like) PeriTriaxController. - TriaxialCompressionEngine and ThreeDTriaxialEngine become almost useless - reflected in the example script which now uses only TriaxialStressController
  • micro-fix (no need to define an initial timestep)
  • code cleaning
  • fix the default value of orientation in utils.box. [1,0,0,0] is NOT a quaternion.
  • add a few python bindings to the periodic engine for manipulations of the internal tesselation
  • fix the detection of (not) already computed tesselation
  • make volume() functional also when PeriodicFlow is actually in use
  • uncouple the compilation of flow code and linsolv, so that it is possible to effectively compile the flow engines without cholmod
  • remove useless "sigma_iso" and "isAxisymetric" members from TTController
  • make an old engine deprecated, not compiled now, to be removed later
  • more #ifdef guards, to allow flow engine without linsolv
  • remove sigma_iso from the triax example script
  • fix syntax error in a doc string (blocking the buildbot https://yade-dem.org/buildbot/builders/yade-full/builds/1741/steps/shell_3/logs/stdio)
  • deprecation warnings in ThreeD and TriaxialCompression engines
  • change the default value of FlowEngine::pressureForce, a flow engine is supposed to compute a flow by default...
  • smallfix in example script
  • 3 new references
  • add "Open Source Discrete Element Method" explicitely in the home page, google has to find us
  • nicer documentation of equations for stiffness definition
  • remove useless #define
  • ship a copy of ipython_directive.py from ipython/HEAD for ipython 0.13
  • ipython version was checked in two different places, forgot the second one. Still no confirmation of the fix.
  • some lines comited by mistake, sorry for that.
  • escape crash on non-iterable __doc__ (some qt class) - define new attributes needed for ipython_directives.py >= 0.13 - fix existing *.rst to use strictly 3 blank spaces in multiline directives (i.e. " ...:")
  • reference name Tran2012a appearing twice -> renaming Tran2012b
  • re-introduce the @supress of Christian (removed during experiments)

  • yet another doc improvement in wrapper and user manual concerning replaceByClumps method
  • replaced errors by warnings in addToClump and releaseFromClump in wrapper
  • Donia Marzougui (5):
  • Fix the computation of viscous forces by using the correct positions of bodies (updated in buildTriangulation), and fix some variable names.
  • Remove fictious spheres from the computation of edge surfaces (employed in the computation of viscous forces)
  • Correct the computation of the viscous and normal stress per particle.
  • Correct the sign of some parameters in the computation of the viscous forces.
  • Correct the normal lubrication force.
  • Francois Kneib (24):
  • Continue the implementation of grids : - add GridConnexion Aabb - add GridNode-GridNode Ig2 functor : Ig2_GridNode_GridNode_GridNodeGeom6D - add GridNode-GridNode contact geometry : GridNodeGeom6D - add an example script : examples/grids/Simple_Grid_Falling.py - update utils.py (minor change)
  • Add the possibility of avoiding the contact detection between a group of particle. -> the vector "avoidSelfInteractionMasks" contains a list of masks : all particles having the same mask will not collide if this mask is inside this list. -> the "mayCollide" method now check this too. -> avoidSelfInteractionMasks can be set in python with a list of int.
  • Add the Sphere-GridConnection frictionnal contact : -> new contact geometry : ScGridCoGeom -> new Ig2 : Ig2_Sphere_GridConnection_ScGridCoGeom -> new Law2 : Law2_ScGridCoGeom_FrictPhys_CundallStrack -> update utils.py to handle the new contact type (using avoidSelfInteractionMasks)
  • Merge branch 'master' of github.com:yade/trunk
  • Add the contact following and avoid multiple contact when a sphere is sliding on a grid.
  • Grids : Fix some minor bugs in Ig2_Sphere_GridConnection_ScGridCoGeom::go(...). -Collider : Change the vector of masks "avoidSelfInteractionMasks" to a single mask "avoidSelfInteractionMask".
  • Create and correct documentation.
  • Grids : - modify the rendering. - Apply correct DEM laws in utils.py to set right kn, ks, kr, and ktw. Now the grid behavior no longer depends on the spacial discretization you make.
  • Modified setContactFriction method. Now it has to be used with an angle in radian unit, no longer in degrees.
  • Try to fix documentation in this files, everywere "yref" appears in the online documentation.
  • Fix Grid periodicity, and allow periodic sphere-grid contacts.
  • Disable a boring warning into the grid construction.
  • Fix a bug in SpherePack.toSimulation. There was a big problem when you tried to add clumped SpherePack (with makeClumpCloud() for example).
  • Corrected toSimulation() (for the last time I hope :-) ).
  • Fix a bug in growParticles(...) method. Growing a clump is now really homothetic. Before that, growing clumps seemed to be homothetic but at the next timestep the original position of members was reseted.
  • Add Inelastic ChainedCylinder behavior law (by Ignacio Olmedo). Create inelastic material and related physics, Ip2 and Law2. Example script and complete documentation will come soon.
  • Add the ability to save to a file a SpherePack containing some Clumps. Into SpherePack : now the toFile method writes a fifth column containing the clump number (-1 if the sphere isn't clumped). The fromFile method uses the new information to append clumped Spheres. Into Shop : loadSpheresFromFile method is modified to read and return the fifth column. Old files with 4 columns are still compatible. Into CapillaryTriaxialTest and CohesiveTriaxialTest : Shop::loadSpheresFromFile is sometimes used here, so remove the clumpId information to match the "BasicSphere" typedef.
  • getStress(...) method : exclude gridNode-gridNode contacts for the stress computing. growParticles(...) method : avoid growing gridNode and gridConnection.
  • Fix some Grids bugs.
  • A minor spelling correction.
  • Add a little class summary and explanations into Grid.hpp. Fix a bug into utils.py when creating a Grid in a non-periodic scene.
  • In the sphinx documentation, add the https GitHub read-only method : git clone https://github.com/yade/trunk.git
  • Avoid GridNode-GridNode contact stiffnesses (kn and ks) to be changed when the growParticles(...) method is used. (GridNodes are not concerned by this method).
  • Add a missing space in the dependencies code lines.
  • François Kneib (1):
  • Correct a remaining bug into the toSimulation() python function.
  • Jan Stransky (9):
  • little modifications
  • added example script for CombinedKinematicEngine

  • complete optparse->argparse, --generate-manpage should work
  • improvement of ConcretePM, remover warnings in pack module (randomDensePack and randomPeriPack functions)
  • modified ConcretePM, corrected Peri3dController related examples
  • Jan Stránský (1):
  • minor changes
  • françois (1):
  • makeClumpCloud(...) now takes a "seed" parameter to generate always the same pack.

New in version 0.90.1 (November 3rd, 2012)

  • It contains only the minor fix: SnapshotEngine did not work in 0.90.0
  • version. Thanks to wangxiaoliang for pointing that out.

New in version 0.90.0 (October 17th, 2012)

  • The main new feature is a moving build-system from scons to cmake [0]. It will hopefully bring better portability of the program on different platforms and operating systems/distributions.
