Hello,

I based my case on the damBreak tutorial, so I am using the interFoam solver. The fact that the Courant number gets so small is probably a sign that the phases are changing a lot, and thus...

Hey! What do you mean by out of capacity?...

Hey!

What do you mean by out of capacity? Have you looked at the interface tension and viscosity ratio of the two phases? This may be the reason for the bubble disapearing, if you are still in a...

For your information:

it is possible to reinitialize the velocity field by using funkySetFields:
funkySetFields -field U -expression 'vector(0,0,0)' -time 0.01 -keepPatches


One can also...

Thank you!

Another idea I got was to initialize the pressure field to be what is expected from theory, by using the formula for pressure difference due to surface tension:

Young Laplace...

Reinitialize velocity field during simulation

Dear Foamers,

I am using the interFoam solver to simulate the fall of a water drop in an oil phase.

For small droplets, I have trouble with initializing the case: I am using the funkySetFields...
