DEFINE_UDS_FLUX in Parallel mode

rafacerq · February 10, 2014, 11:02

Hello,

I'm currently trying to parallelize a UDF code that contains a UDS transport. For my case I need to define the flux, the transient and the diffusion terms of the equation.

When I was running in serial mode, everything went perfect, but now I having a huge problem. The case comparison between the serial and parallel results generate discrepancies next to the cell partitions boundaries, as seen in the picture in the end of the post.

I already noted that the problem is in the DEFINE_UDS_FLUX macro. When I make an analysis between the serial and parallel results, using the mass flow rate for the UDS flux, the results are the same.

Does anyone already came across with a similar problem or parallelized and UDS? If yes, I post the part of my code that's giving me trouble.

Thanks,

Rafael Cerqueira.

Hello,

Did you figure out the problem?
I think I might have a similar problem when I will parallelize my UDF.

Thanks,
Akshay
