Hello all, I commited new versions of NewtonsDampedLaw and LeapFrog engines to SVN today. Using the new versions is highly recommended as the maximum timestep you can use is at least 4 times larger and convergence is faster. I could actually run simulations with dt up to 2*criticalTimeStep, i.e. with globalStiffnessTimeStepper->safetyFactor = 2, correponding to dt 8 times larger than before (safetyFactor couldn't exceed 0.25 with the old leapFrog algorithm). The default safetyFactor is now equal to 1.
Please report any problem. Bruno p.s. If you don't want to update the full yade code, you can always download NewtonsDampedLaw.cpp alone and paste it into your sources. p.s.(2) if you don't know what I'm speaking about, read comments in NewtonsDampedLaw.hpp + discussion on "How to reset a body's velocity?" in yade-users list. _______________ Chareyre Bruno Maitre de conference Institut National Polytechnique de Grenoble Laboratoire 3S (Soils Solids Structures) - bureau E145 BP 53 - 38041, Grenoble cedex 9 - France Tél : 33 4 56 52 86 21 Fax : 33 4 76 82 70 43 ________________ _______________________________________________ Yade-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/yade-users
