Default Solving for turbulence
Posts: n/a
Hi, I am trying to solve the k-w SST model as two scalars. I know it comes with the program but I need to change the VIST values so that only the VIST used in the mean flow equations is changed and not the ones in k-w equations.

I used sorsca.f and diffus.f to model the equation but my result would'nt match with that given the built in SST model. So, I tried to test it with the normal k-e model. And, that does match atall either.... I am including the program from sorssca below. My flow is incompressible AND 2D.

GENERATION=2.0*(GU(1,1,IPSTAR)**2 +GU(2,2,IPSTAR)**2))+ ((GU(1,2,IPSTAR)+GU(2,1,IPSTAR))**2










The results dont look anywhere near the same as that given by STAR CD. Any idea why? I am using the same boundary conditions and discretization details.

Aren't FORTRAN variable names limited to 8 charecters?

If so, your variable GENERATION is too long & may be the problem.

If not, please disregard this comment. My brain is still rebooting from the holidays.
