Anyone knows what do these errors and warning stand for?

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 nan, and lower_energy_value is nan.

0581 WARNING: variable max_temp has been changed from 5.000000e+03 to 6.000000e+04. Continuing with the new value.

The error gives me an abortion in my simulation.
This warning stops my simulation after passing some time steps.

Any idea what they mean?! and how can I fix them?

Hello Russell,

The above error generally occurs when energy goes out of bounds, i.e. there is no temperature corresponding to the internal energy that we are solving for. Please make sure that you are using the recommended settings for solving all the conservation equations, also have a look at the geometry and make sure you have appropriate number of cells for narrow regions of the geometry.

Reasons for having this error can be many and as of now there is nothing much to go on. More details on your case setup would be helpful. If you have low resolution or cell pairing, you would want to fix it by increasing refinement. Double check your case setup and boundary conditions. Are you having any recoveries (check your logfile) before the crash? Is the crash repeatable at the same simulation time in the code? If your case setup matches closely with one of our example cases, ensure that the grid and solver settings are the same.
