Hi Guys! i'm try to create a mesh of a 2d engine, in which i have a simple cylinder and a piston, so two surface. I manage to do the mesh only for cylinder, because next i will do a dynamic simultion. My problem is that i don't want to make another mesh for piston because this will be my moving front, but if i don't do this, ansys detect it as an error. So my question is: there is a way to go on without meshing a surface or i have to delete the piston surface and preserve only its boundaries as moving front?

thank you

Assuming you're using Fluent (it helps if you state which solver you're using) then you need to assign a moving wall to the surface (edge) that represents the piston.  There are several threads on Moving Deforming Mesh on here, along with tutorials on here, YouTube & (possibly) under Help in R19.
