Hello there,<\/strong><\/p>\n

I'm running a case of condensation. For this case, I have run the simulations without any UDF (default lee model), it works fine. Secondly, I run the simulation with UDF containing DEFINE_MASS_TRANSFER and DEFINE_SOURCE macros. The fluent successfully compile the UDF. There is 1 warning though but the simulations run perfectly fine with the expected results. The warning was"<\/strong><\/p>\n

"<\/p>\n

C:PROGRA~1ANSYSI~1v211fluent
\ntbinclang10Include10.0.18362.0shared\basetsd.h(322,12): warning: cast to 'void * __ptr32' from smaller integer type 'unsigned long' [-Wint-to-void-pointer-cast]<\/p>\n

return((void * POINTER_32) (unsigned long) (ULONG_PTR) p);<\/p>\n

^<\/p>\n

1 warning was generated.<\/p>\n

"<\/p>\n

The third time, I use another UDF (completely different from the first one) containing three macros: DEFINE_ADJUST, DEFINE_MASS_TRANSFER, and DEFINE_SOURCE. The UDF compiles successfully with one warning. The warning is:<\/strong><\/p>\n

return((void * POINTER_32) (unsigned long) (ULONG_PTR) p);<\/p>\n

^<\/p>\n

The warning is the same as with the first UDF so I thought it'll also work fine. But upon initialization, the fluent gives the following error:<\/strong><\/p>\n

"<\/p>\n

==============================================================================<\/p>\n

<\/p>\n<\/p>\n

Node 0: Process 17764: Received signal SIGSEGV.<\/p>\n

<\/p>\n<\/p>\n

==============================================================================<\/p>\n

<\/p>\n<\/p>\n

The fl process could not be started.<\/p>\n

"<\/p>\n

I'm running with 1 core only and also hooking the adjust function as well. The UDF is grammatically correct. Still, I don't what is causing this error. Please let me know if anyone knows about it. I'm running fluent 2021R1. Also, the UI of fluent becomes like this after the initialization:<\/strong><\/p>\n
