flotran

Hi, I'm young student from Poland and I've started work with ANSYS not long ago. I'm trying to run a problem with flotran using the element 142 but with moving wall (just like in ANSYS tutorial- 7.6. ALE/VOF Analysis of a Vessel with a Moving Wall). I would like to know how I must set correctly displacement, because probably the problem starts there. Thank you!!!

You need to specify both displacement and velocity in time domain on the moving walls. The Tortional Mirror problem in Sec 7.5 gives more details. Also look into the input command file. I remember those loads are generated using a "Function Builder".
