Hello

I am relatively new to ANSYS Fluent

I was trying to model a system consist of battery pack and cooling plate, the only fluid is the cooling water, while the other parts are solid with defined physical properties.

After I start the calculation, the temperature in some zones went up to several thousand degree, the error looks like this:

"temperature limited to 5.000000e+03 in 78 cells on zone 14 "

But the peculiar thing is, I didn't even define a heat source inside the system. (the initial temperature is 300K and cooling water is even lower-290K)

Could anyone give a clue why the energy increases ?

Thank you very much.
