Is any one know how to use periodic moving wall boundary condition in Fluent? Thanks!

Hi,

I am having the same problem. I think you will have to define a UDF for that. You can refer to the DEFINE macros section in the Fluent online help ( I think it is the sixth chapter- in the UDF manual section).I think it is called DEFINE_CG_MOTION! I hardly understand what's going on there, if you understand let me know.

Thanks

Thank you for your idea, but how I can find the help file?

Fluent Documentation dynamic mesh programming. Look at the separate udf manual about define cg motion, or better at the tutorial about dynamic meshes, this with the valve. If you are not familiar about programming, you have to learn about c++ (a few things) and about udf capabilities. Hope this helps.

I do not have this Documentation about dynamic mesh programming. Anyone can give help on this? Thanks!
