Hello,

I'm new to Fluent and I can't figure out how to fix this error. I have a UDF to set a velocity profile that works fine in serial mode, but when I try to use it in parallel mode, I get the following error:

cpp -I\\d4600\fluent.inc\fluent6.2.16/src -I\\d4600\fluent.inc\fluent6.2.16/cortex/src -I\\d4600\fluent.inc\fluent6.2.16/client/src -I\\d4600\fluent.inc\fluent6.2.16/multiport/src -I. -DUDFCONFIG_H="udfconfig-node0.h" \\d4600\working\swirl100.c

error: udf compiler: cannot execute cpp -I\\d4600\fluent.inc\fluent6.2.16/src -I\\d4600\fluent.inc\fluent6.2.16/cortex/src -I\\d4600\fluent.inc\fluent6.2.16/client/src -I\\d4600\fluent.inc\fluent6.2.16/multiport/src -I. -DUDFCONFIG_H="udfconfig-node0.h " \\d4600\working\swirl100.c

I start Fluent from my working directory and when I try to interpret the udf, it gives me this error. I have been able to run other cases in parallel, but none using UDF's. I would greatly appreciate any help with this problem. Thanks.

Try to compile your UDF instead of interpret it.

Thanks, that fixed it. I appreciate your help!
