hello,

I have a problem with the implementation of the udf

I get the error message "nmake" file cannot be found

any idea how I can fix that

thank you chary

This is quite a common problem, but one that you may be able to fix. Look on Fluent's website or do a search on this website. Be careful to look for "nmake" or "makefile" not "nmakefile".

you need to start FLUENT from VBA.

Sham.

start from visual studio command prompt if using windows
