UDF, about function int Data_Valid_P()
 
Hi, experts

I met a problem in the UDF where I just want to change the 'wall boundary condition'. What I need is the Velo-Slip and Temp-Jump condition which means there is a relationship between the wall-face varibles and the cell varibles... Natually, we can resort to the UDF. I did as the documents said, but the only result I got is the 'fluent received a fatal signal(SEGMENTATION VIOLATION)' which means the cell varibles can't be ready from the memory...

An interesting thing is about the function int Data_Valid_P() which was designed by Fluent to solve this problem. I searched the whole directory .../src/*.h, and I didn't see any proto type definition.

So I really appreciate someone can help me ...
