I was using C_T_RG in my UDF and was getting a similar error & fluent was exiting. Referred to UDF manual and entered

solve/set/expert in fluent panel and turned on

Keep temporary solver memory from being freed? Yes

This was perhaps happening because these gradient values were not being stored for access by UDF.

Worked for me and fluent didn't got killed. But, after initialization, fluent exited again with same error. Any help on this????
