Hi everyone!!

I have solved unsteady 3D navier stokes equations using SIMPLE ..I have attached the code and also the screen shot of Re 1000 at steady state. Mostly the momentum residual is not decreasing with the iteration.

What might be the mistake?


Thanks in advance.

FMDenaro will become famous soon enough
but you are running a steady 3d solver? Are you sure that yout 3D configuration has a physical steady solution?

I am running unsteady solver for a longer physical time until it reaches steady state and am comparing it with OpenFOAM results for the same configuration. But momentum residuals are not decreasing, only mass residual is decreasing with iteration...

I am very sorry I have written the program in C language. I have attached it above.
