Hello all!


I am having difficulty running simulations for my multi-material model.

(Please see attached photos)

Blue region is water.

White region is air.

Green mesh region is permeable PDMS.

Blue arrows are small negative pressure.

Red arrows are larger negative pressure.

So, there is an overall pressure gradient towards the bottom.

Air will permeate into the PDMS part, and water will enter into the hole, replace air, and fill in the hole over time.

I would like to see the water's flow-in velocity and predict filling time.

I have been using ANSYS Workbench Fluent, and I am stuck..

Is this something doable with ANSYS Workbench Fluent? with FLOW-3D?

Can someone help??

For the purpose of carrying out a reliable numerical simulation, and the mathematical model which describes the physics should be scrutinized.

For instance, transition among phases such as condensation, requires an appropriate mathematical model, correlation, or theory which defines the condensation process as accurately as possible.
Generally, the modeling process of multiphase flow includes three main stages, which are the description of the physical process, and specification of the flow, and the determination of the suitable mathematical model.
