C_UDMI and *rr showing different values

nofugz · June 16, 2024, 13:43

Hello all !
I wrote a small UDF for calculating volumetric reaction rate using DEFINE_VR_RATE. In the code I store my VR function in a UDMI as I require to use it in source terms elsewhere. Simultaneously, I say that that *rr = C_UDMI, to update the reaction rate in the system. Now when I check the contours the UDMI and default reaction rate contours look totally different ! I would like to know why is it so ?

Similar issues have also been found, and the cause is still being investigated
