[modigliani]

Hello people,

I simulate of fluids pumping in tank without inlet and outlet. There is propeller under free water surface and this pump pressures the liquid back into the tank. I used interFOAM solver and OF v2006, but there is starting error. Unreasonable low Co number and timeStep continuity. Could anyone help me ?

Thanks

Modi
