i have a 2D axisymmetry problem
and i have used the dynamic mesh with the option remeshing and smoothing
the inlet is a pressure inlet ( transient profile)
outlet (pressure 0Pa)
walls ( stationary)
a piston as a rigid body ( with stifness and preload)
i don't know what's wrong ?
any ideas?
thanks in advance
