 September 4, 2008, 12:44 Problem with moving mesh #1 Sully Guest   Posts: n/a Sponsored Links I am trying to use a moving mesh to semi-steady state flow thru an orifice at various spool positions within a valve. I have set the boundary condition of the moving wall to .00005m/s to simulate a very slow moving wall. Next I am setting the time steps to 2sec and trying to solve for 15 positions (every .1mm). When I preview the moving mesh, the actual travel is orders of magnitude higher than what it should be. I am using Fluent 6.2.16. Please Help!!!!
