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.
