regarding convergence
Hello all i am new user to star ccm+ . and i am working on a offshore structure tension leg platform . when i am running the analysis the momentum's (x,y,z) are not converging .can anybody can help how can i converge these momentum's.
there are so many options like
1) changing the mesh
2) Time step
3) relaxation parameters
what what can i do and how ..well i tried all of these somehow but i am unable to do.
Please help me out.

First, please put a picture of your residuals.
Then, What is your surface mesh quality?
If the mesh is complicated, try to run with first order convection shemes. Go to Continua/ physics and click on the models.

I have attached the residual picture. and the surface mesh quality .
