moving mesh and free surface

July 5, 2001, 14:31

hello, is there anyone who made a model with moving mesh and free surface. i tried to simulate a moving ship in a channel with free surface, but the calculation terminates with the message: U-MOMENTUM EQUATION NOT CONVERGED, MAXIMUM SPECIFIED CORRECTOR STAGES 50 REACHED BEFORE. i´ve also raised the corrector stage up to 100, but no improvement.

thanks

Hy, I'm trying a similar analysis with a ship and my solution converges, even though I haven't verify the results because post-processing in Star is really poor.

What kind of cells are you using? What boundary conditions? Are oyu using, moving mesh or VOF?

See you Giovanni
