Moving Dynamic Mesh in Fluent 6.2
 
Hello Fluent Users

I'm trying to model a moving deformable mesh in Fluent 6.2. The problem is that the case study (tutorial) that Fluent has provided seems difficult that involve a complicated grid, turbulence and... to follow for a beginner like me to MDM problems. I tried to perform this task on a simple rectangular grid in which one of the edges has to move and deform the bottom axis. The UDF they provide is hard to read and when I somehow set the problem in fluent, the next issue in queue is the dynamic meshing and smoothing for prscribing the dynamic mesh parameters. I get a message like "non-positive volumes exist". I dont know how to fix this and what causes this! Also, what is procedure for specifying an interface?

Anyone has ideas, please send me e-mail.

Thanks in advance for your attention to this matter.
