Hi

I would like to know if for version 5.3 of comsol the term of gravity is already enabled. If is not, is there any way to solve this problem?

I was studying the tutorial of the applications gallery "Two-Phase Flow Experiment" and I am confused because hydrostatic pressure is applied with a minus sign, would someone explain to me why?

Thank you

Hi Sebastian,

For manual gravity declaration, you can use volume force and specify F = mg. Hope this helps.
