Yade 0.97.0

Yade is an open source and extensible framework that can be used for discrete numerical models, especially designed for the Discrete Element Method.

Yade's computation parts were written in C++ with the help of the flexible object model, which allows independent implementation of new interfaces and alogrithms.

Bruno Chareyre (21):
· Fix (partly) https://bugs.launchpad.net/yade/+bug/1009257, still not good with clumps
· avoid deprecation warning when using the triax preprocessor (the future of preprocessors is not certain, though...)
· fix https://bugs.launchpad.net/yade/+bug/1115554, removing the extra variables
· tutorial script: replace L3 geometry by ScGeom
· tutorial script: increase O.dt again, no need to slow down
· adjust number and size of clumps in the periodic cell
· fix two crashing typos in triax-tutorial
· PeriodicEngine check if simulation time has been reseted (fix https://bugs.launchpad.net/yade/+bug/1153528)
· small fix in the way TriaxialStressController defines meanStress
· A more precise integration of contact forces in periodic deformations, using period size of the previous step for the relative velocity update + cache a (matrix x matrix) product for performance (previously re-computed for each other interaction)
· fix a small bug in the determination of the mean stress (TriaxialStressController)
· a more flexible implementation of density scaling
· get back gravitational wotk in NewtonIntegrator (removed by mistake in previous commit, sorry)
· reflect (1) in regression tests, since they were expecting innacurate values, cell size change only in the next step after velGrad assignment. (1) https://github.com/yade/trunk/commit/422ecb00c710337ede7ace6ae62f8f857c6e975a
· small fix in doc hyperlinks
· two additional bib articles
· A more accurate integration of external work input in PeriTriax engine
· Handle errors in fluid engine more nicely. Pause the simulation when something goes wrong instead of crashing...
· update cell's prevVelGrad in Newton
· fix two compile warnings
· better error handling in FlowEngine - remove lubrication forces between spheres in boundaries - check that id1!=id2 before computing forces (can happen in very small periodic packings) - some code cleaning (FlowEngine.cpp)

Francois Kneib (4):
· Change the growParticles method behavior on clumps into Shop.cpp. Now the clumps are not grown if the clump members are fixed (i.e blockedDOFs='XYZxyz').
· Workaround for a Ubuntu 12.10 bug that gave a segmentation fault when launching Yade. The importation of "_io" is made sooner, at the beginning of yade python executable. Changes applied to core/main/main.py.in.
· Handle the cohesive contact between a sphere and a facet. Created Ig2_Facet_Sphere_ScGeom6D inheriting from Ig2_Facet_Sphere_ScGeom. It precomputes the 3 rotations DOFs and creates a ScGeom6D contact geometry. All modifications made into /pkg/dem/Ig2_Facet_Sphere_ScGeom.cpp and hpp.
· Changes in Grid.ccp/hpp. - Improve documentation for Ig2_Sphere_GridConnection_ScGridCoGeom::go() - Add a new law (Law2_ScGridCoGeom_CohFrictPhys_CundallStrack) that allows a cohesive contact (without rotational moments) between a Sphere and a GridConnection.

· improved damage tensor computation in CPMState
· doc improvement: added importing yade into user's manual, corrected index notation in utils.bodyStressTensors functions
· correcting compilation errors from previous commit
· fixed bug in Cpm for Sphere-Facet interactions
· fixed bug in Cpm, now for Sphere-Wall interaction
· disabled some prints for non __main__ yade imports

· added ymport.iges function for reading facets from .igs files
· updated timing documentation
· updated documentation (due to recent changes in Cpm), corrected Cpm related examples

Kubeu (1):
· added some hints about plotting and batch mode

christian (3):
