[gmx-users] Incorrect number of parameters - found 3, expected 1 or 1 for Polarization.

[折晓会]

Thank you professor Justin! I solved this error which comes from the decimals of the box dimensions. Initially, my box dimensions are 4.5*4.5*16 nm3 and the local pressure calculation does not work, but after I change them to be integers 4*4*16 nm3 in the gro file, the simulation works. It is strange for me. I do not know why. 

Best wishes,
Xiaohui
