Hello actually i simulated a Natural convection concentric cylinders problem when i wanted to find average nusselt number i find -1.#IND displayed for some of the faces please help me know what is this

Was there any problem with your simulations? Did it converge properly?

Sir my solution is converged i checked the energy balance but when i want to find average nusselt number that time i am getting that value

i think you have put a valur of 0 somewhere where it should not be. this happens to me if i forget something...
