I double-checked scripts/test/periodic-triax-velgrad.py; the reason it was shrinking vertically is that there was PeriTriaxController engine doing the shrinking. If disabled, shear is pure for the case I mentioned. To me it is not clear what is the advantage of multiplying velGrad by trsf before applying it, but I don't mind actually, if it works. Is the velocity gradient what they call like that in http://ocw.mit.edu/NR/rdonlyres/Earth--Atmospheric--and-Planetary-Sciences/12-800Fall-2004/C6754086-6D62-4354-BB9A-1E8AEF4B4967/0/lecture5.pdf (sect. 5.4) ? v. _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
