07:53 PM GROMACS Bug #2862: Division by zero in restrained dihedrals

For sure the code is not sufficiently robust. Maybe some variables need to be made double precision.

07:02 PM GROMACS Bug #2862: Division by zero in restrained dihedrals

Here is an issue related to the same code, where single and double produce completely different results.
