Default piston movement
Posts: n/a
I have a simple theoretical question which i can't answer. How we solve the motion of a piston, when the latter attaches the bottom of the cylinder? We all know that this leads to a negative volume message (the fluid cells doesn't exist more)! how we deviate this problem?

*Assume that i want to solve it with dynamic and not deforming motions.
