UDF received a fatal signal（segmentation fault）
 

Hi！
I successfully compiled a UDF about DPM using "Transient Calculation". During the calculation：
the error appeared as shown below:
Error: received a fatal signal（segmentation fault）
Error: received a fatal signal（segmentation fault)
Error object:#f

I checked the code and I think it's right.
who can help me? Thanks!

Difficult without the code. But generally, a segmentation fault means that FLUENT is looking for something in the memory that is not there. IT could be unintialized, it could be a wrong thread reference (are you running multiphase? Make sure you are pointing to the right phase threat), it could be an unassigned UDM
