I have been trying to figure out whether or not it is possible to set Pstart as a variable in fix press/berendsen. I see in the documentation that it is possible to set Tstart in fix temp/berendsen as a variable for time dependent temperature, but that is not directly stated for pressure. Thank you for your kind attention.
If it is not mentioned in the documentation then it is not possible. We have the requirement that no feature gets added to LAMMPS without being mentioned in the documentation.
Thank you! I appreciate the clarification.
