You mean domain decomposition.
Yes, sorry!
By imposed I mean that the flags are explicitly changed to do angular
removal of
COM (remove the rotational momentum) even if it is not the case in the
mdp file.
The code itself of not modified to do implement it!
You'd find in the lines like this:
if ( mean_field ) {
ir->comm_mode = ecmANGULAR;
ir->nstcomm = 1;
}
The question really what the code is then doing is asked to remove the
rotational momentum
while not implemented! The code is stable for micro seconds!
It is so as the mean field stuff was imported from earlier gmx
versions where the particule/domain
decomposition were not implemented I guess.

What do you mean with "imposed"?
If you impose it correctly, it would of course work.
