Hi,


grompp show the error as below:

ERROR: pressure coupling not enough values (I need 2)

I used ref_p       =1.  In  file.mdp

How to solve this problem?


Without seeing the rest of your pressure coupling settings, I can only assume that you're using semi-isotropic coupling, and thus, per the manual:

"Pressure coupling which is isotropic in the x and y direction, but different in the z direction. This can be useful for membrane simulations. 2 values are needed for x/y and z directions respectively."

thanks in advance,
