Bubble Column: Initial Condition for Inlet

deborahgomess · May 15, 2015, 12:12

Hi foamers,

I'm a newbie in OF and I have this (probably) primary doubt about boundary conditions.
I am simulating a bubble column like the tutorial one (twoPhaseEulerFoam). There, the air entry is set in the entirely inlet, but I want the air to entry only in the center of the inlet patch. I tried to modify the blockMeshDict and the setFieldsDict but with no succeed. How can I set this?

Thanks already,

Deborah Gomes

Thank you! I was able to set a non-uniform condition in the inlet specifyng alpha in each cell in the inlet. It was not exactly what I was looking for, but it fix well to my case.
