Task #1785
no pV term written to energy file when pressure coupling is anisotropic
Description
In https://gerrit.gromacs.org/#q,I157b0468907802e29c7dec763ed2e5db99c02922,n,z a fix made explicit that we only write a pV term to the energy file when there is isotropic pressure coupling.
Whether we can and should write a pV term for non-isotropic coupling is an open question.
