Oh, yes, uncoupling trsf and the rest is easy. trsf and Hsize are
uncoupled in Yade code already, and refSize is not used. The only
problem is existing scripts are assuming a coupling, and they use refSize.
I just added a transitory "resetTrsf" function that you can use for
resetting tsrf (r2674). It will do the same as trsf = identity without
the side effects: you don't have to modify refSize or to use the
tempHsize trick above. You type O.cell.resetTrsf() to make the current
state the zero-strain state, and that is all.

Cheers.
