bubble penetrates wall DPM

zdunol · January 11, 2016, 13:25

Hello,

I'm playing around with discrete phase modelling, I created a simple case where I inject a bubble into a pipe, naturally bubble moves upwards due to gravity. Unfortunately when it encounters a wall it penetrates it, no matter which boundary the wall has

Does anybody know what am I doing wrong?

reards,
Zdunol

ok it doesn't penetrate the wall it just gets very very flat so I didn't see it. I also sometimes "filled" option doesn't work when I try to plot contour plots and I see evgerythingv in mesh-wireframe way (that's why i didn't see the bubble I guess), does anybody know how to fix it? Reinstalling fluent didn't help ;c

I think you must select reflet bubbles in the boundary conditions, it works.
