i use a experssion to express specific heat capacity changes with Temperatur(just like gauss distributing),but there is a notice appeared. ****** Notice ****** | | While evaluating Temperature, | | Static Enthalpy on domain hotair | | went outside of its lower limit. Its minimum value was | | -1.1202E+08. The bounds error was handled by extrapolation. | | If this situation persists, consider increasing the table range. i try to changer the table range in the material properities, (intrease the temperature range),but the simulation result seems unreasonable? what shall i do?

This expression, appers alwys when you've to take variable Cp or density depend on pressure and (or ) temperature. If this message disspears afetr a few iterrarions (2 or 3), it will not be a problem, and no influence on your final results Best regards

but in my simulation,the notice didn't disappear, and the result was wrong apparaently. what shall i do?

As the warning says, go back to your fluid property definition and set a reasonable table range.

OH MY GOD ITS SOOOOOOOOOOO HOT
