Have you specified a variabel called THERMX? You will have to post your whole CCL for us to help I suspect. Also a diagram of what you are modelling would help.

like "828 00". This will cause problems in CFX, but this maight be just an artefact of copying it into the forum. If that is not the problem I would go through your CEL one function at a time. Replace a function with a constant value and see if it works. Then you should be able to find the function which is causing the problem.

Have you solved the problem yet? I got the same error saying " Error finding variable 'THERMX' " when I just do a thermo-hydrodynamic simulation with adiabatic walls.

PS: Well, I think I figured out. I got this error when I tried to monitor a force. I fixed it by cancling the user-defined monitor.
