Hello everyone
Im trying to simulate a siphon using interFoam as my solver. I have finally gotten it to run, but forgot to set my internalField in the alpha.water to 1.
i then fixed this, and now my simulation only runs for 4 time steps, before it stop without any warnings og messages. What could be the course of this??
