Parallelizing a udf

coolengineer · April 27, 2009, 13:09

Hello,

I have a working udf. How can I use this udf for parallel computing. I have a look at the udf manual in Fluent. But it is quite complicated. What do you suggest me to do?

Waiting from you.
Thank you.

If you post your udf, maybe somebody can help you.

It is a simple CG-MOTION UDF.

Hello coolengineer,

I think a really simple CG_MOTION (i.e. linear velocity or omega are given and not computed in some sophisticated way with data from cells that may reside in different partitions) will not require any parallelization of the code by you. Just compile it in parallel mode and run the case.

cheers

hi

I have code which is working on serial but doesnt work in parallel. I am using execute_end function to save outlet mass flow and then by using define_profile function and saved data,I am giving my inlet BC.
do you have any idea about problem?
thanks in advance!!!
