Error in using UDF

ati85 · August 28, 2011, 17:45

Dear all,
I am working on a 2-D modeling of slip flow. When I want to set my boundary condition through using UDF files ( Slip velocity and temperature jump at wall) I face this error:

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: ()

I have saved my case under new name also I have changed my mesh. What can this error mean? How can I fix it?

Thanks in advance.

You should do pre-iteration or patch.
BTW
Could you share your udf?

This error is a result from an infinity of possibilities. if possible, post your code so we can have a look and suggest something.

This is a post from almost 5 years ago. It is the only post this user ever made on this forum. So I don't expect he will come back to share his code.
