UDF and the wall treatment problem
 
Dear all,

I want to set the calculating region into two layers, the main layer is planned to use the stand k-e model, and the near-wall region want to use a low Reynolds numbers model.

The problem is that how can I use UDF to integrate the two model?

Best Regards!
