Hello everybody,
i am trying to simulate boat sink and trim...i'm not interested to define good results for the transient and i would like to know what's tipically the max number of inner iteration for such a case. Iam using 5 iterations per time step...do you think it is sufficient to define correct sink and trim value??or may i risk not to converge? Many thanks |

I used to use a 5 or 10 iterations per timestep and solver always converge correctly. I think 5 is a good one in this case.
Do you how to create a control volume in star-ccm+? |

I use half geometry for simmtrycal flow or whole model in such a case as manouvering where unsimmetrycal flow. |

How do you substract from the block surface the geometry of the model. Because you have to do this in order to process symmetrical flows, haven`t you?

i generally build a block surface and i intersect it with my hullshape...than i will cut the block by edges from intersection
