Message #02911
[Branch ~yade-dev/yade/trunk] Rev 1936: 1. May fixes for errors found when running larger simulation.
------------------------------------------------------------
revno: 1936
committer: Václav Šmilauer <eudoxos@xxxxxxxx>
branch nick: trunk
timestamp: Sun 2010-01-03 21:30:24 +0100
message:
1. May fixes for errors found when running larger simulation.
2. Move material properties from Ip2_CpmMat_CpmMat_CpmPhys to CpmMat itself.
3. Some reverts in PeriIsoCompressor (log strain and usage of refSize)
@Bruno: fell free to undo my diffs on PeriIsoCompressor, I am aware exact implementation should be matter of ongoing discussion (better on the list than by comments in the code perhaps).
