How to locate all the edge node by UDF?

hadesmajesty · August 5, 2013, 12:00

Hi, I want to implement Womersley velocity profile on inlet of a 3D vessel. However, the inlet face is not strictly a circle, so I need to map a profile for circle to the non-regular inlet face. The implementation involves finding the nodes on the edges of inlet face, which means the nodes on the vessel inlet and vessel wall.

I am wondering if there are any Fluent udf macro can do this or how to write a code to locate (get the coordinate) all the edge nodes? Thank you in advance.

Have a look at macro C_FACE.

Also look at these pages
