error

Hello
In every RANS model I run, my program aborts with this error:

ERROR: Something is wrong in function get_temp_from_table_massfrac: upper_energy_value must be greater than lower_energy_value!
upper_energy_value is -1.#IND00, and lower_energy_value is -1.#IND00.

I came upon this problem when as a comparison I made changes to my turbulence model from LES to RANS. It must be noted that my LES model ran with no problem and my results were consistence.

what does that error mean for my RANS model and what should I do to resolve it?

Hi, Mohrezk,
That normally means the energy solver did not converge. Can you give us more background on what problem you are solving? If you like, you can send your request via your official email to support@convergecfd.com and some of us will help you out. Thanks.

thanks for your help
according to your tip I changed the solver equations for energy and density to BICGSTAB and it is working.
