Your code excerpt looks fine. The only potential issue I can currently suspect is that you did not declare the
descriptors::FORCE field required by the
ForcedBGKdynamics dynamics in the
NSDESCRIPTOR. This is not necessary and would work if you actually explicitly initialized the field in your code (which would transparently allocate it). However, if it is not declared and not initialized this could potentially cause an access error depending on the platform (which would of course still be a problem to be fixed with a better error message).
If this is not the cause I’ll need more details / a full code example.
