would u please if u have an idea to explain to me what is the meaning of the fluent massage during iteration: temp limited to 5.0000e+3 in 1200 cells on zone 2 in domain 1. thanks in advance zubier

Hi, Beacuse of some reasone while solving the energy equation the temperature is few cells is going above 5000K. So Fluent will automatically correct them to 5000K. You can changes this limit using Solve --> Controls --> Limits.

This option is very usefull in increasing the stability of the solver. If we have some knowledge about the flow we would be knowing the max and min and values the pressure and temperature can reach. By setting these as limits the stability of the solver can be improved.

thank very much Venkatesh for your answer but i have other question when iam doing iteration i see this massage, and the solution dosn't converged even i repeat the iteration what this means thanks
