Default Calculate Pressure force
Posts: n/a
Hi all,

I have a piston-volume setup. The fluid is a user-defined fluid using the 'user-defined-real-gas model' which restricts me to the coupled solver. I am able to compress the fluid using a prescribed wall (piston) motion.

I would like the pressures developed in the volume to influence the motion of the piston. As i understand it, the pressure force acting on the piston wall can only be calculated if the segregated solver is used (using the F_AREA command in the UDF). Is there a way i can calculate the pressure force acting on the piston wall while using the coupled solver?

Thanks in advance andy
