Default velocity field divergence?
Posts: n/a
Hello there,

I've recently ran a simulation which seemed to work fine. Now, after making a slightly smaller version of the model, it won't run and i keep getting the following message:

Updating solution at time level N... Error: Too many (0) VOF sub-timesteps. The velocity field is probably diverging. Please check the solution, and reduce the time-step if necessary.

I presumed this meant that i had to change the time step in the 'iterate' section, but this doesn't seem to work??? I've double checked all my parameters and they are the same as the last simulation i preformed. Could this be a mesh problem?

Thanks in advance for any advice!
