Convergence problems
I'm currently experiencing some problems in reaching the convergence in STARCD calculations. I have already tryed to reduce the mesh size and/or to change the boundary conditions to help reducing the residual values, but after some iterations, they always start obscillating between 10^1 and 10^2.
Is there any trick I can use to solve this problem? Thanks a lot. Simone 
Re: Convergence problems
Is your problem really steadystate?

Re: Convergence problems
Yes! It is a really steadystate problem!
Can you help me, please? Simone 
Re: Convergence problems
To me it looks like your problem may be a REAL transient and you try to enforce a steadystate solution. That may be the reason why you cannot get a converged solution, because the flow physics may be wrong.

Re: Convergence problems
It's possible! How can I have a transient solution?

Re: Convergence problems
Change the analysis type from steadystate to transient?
