Hi everybody
I wrote a UDF, compile it and load its library without any problem. But when I want to initialize the UDS parameters which I defined in my UDF, I face to 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: ()

What should I do to solve this problem?

Hi,
It will be difficult to help you without seeing your code.

Meanwhile if your code requires allocating UDM you may need to specify memory/node locations in the GUI.

Another point is if you compiled in a different machine or on different number of cores to the current machine, you will get some errors.

You could also get Access violation error if you attempt to call a variable that is not available in the solver. For example if you are running an isothermal problem and you attempt to call temperature C_T or you are running a laminar problem and you attempt to call turbulent kinetic energy etc.

Hope it helps. Cheers.
