Hello, everybody!

I've been trying make a simulation, using the 6DOF udf, putting obstacle in the shape of circle ( each one with your udf) in a canal and allow them to have the freedom to rotate around its axis of symmetry. Everything was fine, however now that I added more a few obstacles, the following error appear:

Stack backtrace generated for process id 18775 on signal 1 :
/ansys_inc/v130/fluent/fluent13.0.0/lnamd64/2ddp/fluent.13.0.0[0x12afebd]
/ansys_inc/v130/fluent/fluent13.0.0/lnamd64/2ddp/fluent.13.0.0[0x12b04e3]
/lib/libpthread.so.0[0x31d360ea80]
/ansys_inc/v130/fluent/fluent13.0.0/lnamd64/2ddp/fluent.13.0.0(c3+0x0)[0x1ad3b68]
Check the file fluenterror.log for details.
================================================== =============
Error: fluent.13.0.0 received a fatal signal (SEGMENTATION VIOLATION).

I realized that the error appears only with some UDFs (e.g., with the obstacle c3), but don't understand why, they are equal. Does anyone have any ideas?

I don't understand, but I changed the name of udf and the problem was resolved. I think is a bug of fluent.
