i want to model a flow through a air filter. air filter contain more than 300 thousand nano tubes. how can i make geometry of this any idea. Thanks Anjum

Hi!

I think, you can not model the geometry in detail. If you use for every tube minimum of 100 cells, that results in 30 mil. cells total!

Suggestion: model a little number of nano tubes (a few hundred), take the results and put them into a porous media model.

Hope it helps
