We use Fluent 17.2 in our University.

I have a udf file that interpret works fine in university's windows cluster in parallel mode.

but in Linux(CentOS 7) base it shows error like this:

error at node 004: error: udf compiler: unable to open udfconfig-node.... for write.

error at node 123: error: udf compiler: unable to open udfconfig-node.... for write.

error at node 056: error: udf compiler: unable to open udfconfig-node.... for write.

...

What is the problem?

all my files are in a shared working directory with read/write/execute permission to all.

In Serial mode it works properly!

1/Centos was not supported for R17.2: So do not expect that it has to work or tht someone might help you there.

2/I would first try to copy only the case and the UDF file and try to interpret (not other files) to check if it is a configuration issue

3/Why not compling on Linux?

Best regards,

Amine
