[gmx-users] Surface tension coupling with Parrinello-Rahman algorithm

[Giuseppe Léonardo Licari]

Dear André,
In that publication it is specified the use of semi-isotropic pressure
coupling, not the surface-tension option in Gromacs. They were controlling
the surface tension applying a different pressure in XY than in Z. But I
guess it still different from my question, which is related to the
surface-tension option instead.

Regards,
Giuseppe
