3D ship model sim
 

Good morning,
I'm running a 3D ship model simulation, scale 15 ( 3.6m model), k-e turb.model, velocity: 1.329 m/s, in order to verify resistance. Physical time 20 sec, 3 step iteration, 0.01 time step. In the first simulation (pics. 1~2) at 16.5° second, it appeared a trend change in the resistance and residuals ( as if someone stopped the running),while in the attempt n.2 (pics. 3~4) it appeared on the screen, at time 3.44 sec, the error "amg solver diverged", and "a floating point exception has occurred"...
Can anyone help me?
Thanks

Your case just blew up. You need to find out where it blew up - look for unphysically large velocities or pressures. What does the grid look like in that location?

Check your inner-timestep convergence. Do your forces converge?
0.01s per timestep seems pretty big.

Ok, thanks, sorry for my late reply, anyway I solved the error.
