An error about Unphysical field variables detected on one or more processes

Hello,
Renctly,I did some changes mainly about regions,not CP or other parameters,but there occured this error:
8_034)FG``WE9JL`OOA11
What’s the problem?
Thanks for your help!

I am afraid there is not enough information. What did you change exactly between the case that ran and the one that fails? How soon does it fail? Looks like you are using MFiX 21.3.2. Prior to 22.1.1 there could be cases where the Cp was not defined properly and it could be set to zero if the temperature exceeded the Thigh value and all High coeffs were set to zero.

The best I can suggest is to use 22.1.1 release and check that the Cps for all species are defined properly (you can plot cp vs. temperature from the GUI).

Thank you jeff,I have found the problem,The temperature range of the Cp of a substance is less than the maximum temperature that I set .
