Dear colleagues,

My fluent simulation was running on station and it was a UDF based fluent run on station and changed my system to a cluster of stations.

As computation system has changed, my residuals have changed significantly.

Unfortunately, I don't no architecture of computer well.

my question is:

Is parallelization a cause for change in error?(there is an odd experience that run UDF in parallel may cause to a different answer with serial!)

Thanks in advance
