I performed a wave-function optimization, geometry optimization, cell optimization, and a NVE ensemble calculation all using the module. However, now that I am running the NPT calculation using the module it seems to hang. It reads in all the parameters from a previous restart file, it starts to initiate the process but gets stuck in the SCF optimization routine.
