[Bug 1381282] Re: Sign convention in TriaxialStressController not consistent ?

 

I copy paste below some part of the build/CMakeCache.txt (also attached
as a whole). I guess that's what you wanted. And indeed the same
discrepancy in Q (with the same INFO message) appears for another
version without any change in sign convention

//No help, variable specified on the command line.

//Enable CGAL

Title:
  Sign convention in TriaxialStressController not consistent ?

Status in Yet Another Dynamic Engine:
  New

Bug description:
  Hi,

  When used as stress or strain rates, sign convention of "goal1/2/3"
  attributes of TriaxialStressController engine seem to me as not
  consistent.

  Positive values for stress goals correspond indeed to compression, whereas positive values for goal strain rates involve extension.
  Which is itself not consistent with TriaxialStressController.strain variable (in the end, to obtain positive TriaxialStressController.strain, you need to set negative strain rates goal variables).

  Not difficult to fix, but maybe require a common decision. (I vote
  myself for geomechanics convention)
