Piston Motion
 

I currently have a 2D mesh and would like to turn one edge into dynamic mesh with piston motion. I believe you can do that on Fluent but I'm not sure now. Can anyone enlighten me?

I think its better to create dynamic mesh in Gambit or in any other grid generating software and assign your moving part a different zone.Then import it into Fluent and link a UDF to direct the motion of piston..

hello usman, i got a udf which makes the piston oscillate vertically.what the change we will do if we want to make it oscillate horizontally.i want to make it for a horizontal compressor.please help me.regards...
