I am running Fluent 2020R2 on a Linux system. I am able to compile the UDF using the instructions given in the Fluent UDF Manual. But when I start the simulation, it throws a segmentation fault and corrupted double linked list error. I did not face this type of issue on a Windows system when running the same case and UDF. Can someone please tell what might be the issue? Any help is much appreciated. Thanks.

Is it the same case and same UDF you are trying to compile under Windows and Linux? If yes: please check with IT / System Adminstrator. 

Please share screenshots of Fluent Console when you compile under Linux and running: perhaps there is something written which might help debugging the issue.

Hi DrAmine. Yes it is the same case and UDF I am trying to compile on the Linux system. I will share the screenshot.
