Hi *, I want to use two UDFs in a single geometry. Does anybody know if it is possible?

I have a simple channel, and I want to define one UDF on the top wall and another UDF on the bottom wall.

Please reply if you have any idea about it.

Thanks.

I was trying to do a similar thing. I found that I could only put 1 udf on any one boundary condition (however it may be possible to different types of udf (e.g. velocity and a property) on a single b.c.) Therefore you can just define 2 different boundary conditions for each part..and 2 different udfs and then just set them up in the boundary conditions. Glenn

Use two function in same file. Give different name to each function. It will definatly work. If you any doubt reply me with your problem in detail Regards, Rahul

You have solved a big problem that I was facing. Thank you Glenn and Rahul. I really appreciate your replies.
