Temperature gradient: Does the C_T_G macro work ?
Hi CFD mates,
I want to compute the temperature gradient in different solid zones of the domain. I found that the macro C_T_G can perform this task but I did not manage to get it working. Fluent always gives the same error: "Segmentation Violation"
Why ? How to solve this issue ?
I have looked here and there on the internet and I found many people who have the same problem, but I couldnt find any solution. Is it possible that there is a problem with the macro C_T_G itselft ?
Here is my code (which is basically the same as in the UDF guide of Fluent):
d = Get_Domain(1);
C_UDMI(c,t,1) = NV_MAG(C_T_G(c,t));
Thanks mates !
Did you add header file mem.h in your udf?? and also did you run the text command solve/set/expert??
This will Keep temporary solver memory from being freed?.
Note that when you do this, all of the gradient data is retained, but the calculation requires more memory to run
