Invalid thermal boundary condition

July 4, 2008, 05:47

hi, i'm having problems with few region with 'invalid thermal boundary condition'. i have check the selected boundaries and the values but the problem is still there.please advise on how to detect the problems in a proper way? currently i am running conjugate problem with multiple materials.

please advise.

thanks.

Hi

I guess that you are using STAR-CD 326 and you see an error like

*** ERROR #320 *** INVALID THERMAL BOUNDARY CONDITION AT REGION 3

If so then you can turn on the option

Anaylsis Controls | Output Controls | Monitor Numeric Behaviour | Print Boundary and Body Force Information.

If you try to run the case and look in the info file now you will see the offending cell where the boundary is located.

I hope this helps.

thanks steve,

now i'm trying the simulation with a simple model on how to solve the problems.
