sub-timesteps
 
Hei, i simulate air-water flow in the circular pipe and after som simulations get the following message:

Error: Too many (1813) VOF sub-timesteps. The velocity field is probably diverging. Please check the solution, and reduce the time-step if necessary.

Does anybody knows what is the reason?

Thanks
