Floating operating pressure
 

Hi all

I have a closed volume-piston arrangement and would like to compress the fluid inside slowly. The Floating pressure option seems to be only available if I specify the segregated solver and an ideal gas. I would like to use the user-defined real gas model, but this only works with coupled solvers. Is there anyway to force the floating pressure option or another way around compressing a user-defined fluid in a closed volume

thanks in advance antun
