Hi, This message is for Triaxial lovers. Changes appeared yesterday(*) in trunk, and should be reflected in a coming release prepared by Anton. The idea was to simplify the control of boundary conditions.
Previously, ThreeDTiaxialEngine (1) and TriaxialCompressionEngine (2) were the two reasonable options to simulate triaxial path. Both engines inherited from TriaxialStressController which was the core part controlling stress. With yesterday's changes, it is easier to use TriaxialStressController directly as not only stress but also strain rates can be prescribed independently on each axis. The interface follows more closely (but not exactly) the logic of the periodic boundary controller PeriTriaxController. The tutorial script is updated (**), it is no longer using ThreeDTiaxialEngine. I tried to keep the behavior of (1) and (2) unchanged but since they inherit, it is possible to find difference in a few special cases. If you have troubles in your older scripts don't hesitate to ask for help.
