Dears,

It's more than years that I don't use GMX on regular basis so my memory is leaking here.

Is there a recommendation that once using conjugate or bfgs for minimisation then one have to set "constraints = all-bonds" in the mdp file?
And if using steep then one have to set "constraints = none"?


The opposite is true in older versions. In the newest version (3.3.3), you can use constraints with CG and L-BFGS, as well as steepest descents.

I just don't remember where I saw something like this. Any comment here would be very appreciate.

Many thanks in advance,

Alan
