interpreting udf

rostamimass · April 28, 2011, 04:27

dear all
i have written a udf that contains some functions for example source-u momentum and source-v momentum. once i interpret them individually (i.e. in 2 separate udf source) there is no problem in interpreted them, but just one of them is visible to hook to fluent, so i decided to combine them to have one source. now there are some errors to interpret it, i don't know why and what should i do?

thanks in advance.

Hi,
by compiling them, you'll get rid of such problems.

thank you very much for your replies

.
fortunately this problem was solved. now i want to solve a 2d model using that udf but there are following errors:
Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: ()
The system cannot find the file specified.
what should i do?

thank you very much.
