May 15, 2017, 09:43	A UDF for piston motion in dynamic mesh	#1
aminepoxnet New Member amin masumi Join Date: Jul 2012 Posts: 17 Rep Power: 13	Hi every body I use fluent for about 6 years but I'm new to UDF. I never have used any UDF and now in a transient structural and fluent coupling I need to use a UDF to just move the piston. I mention that my geometry is a simple cylinder and piston model. I used some UDFs but the piston doesn't move. Can any one help me? Thanks!
