contact detection and porous zone
 

Essentially, I'm trying to simulate contact between two surfaces which will stop fluid flow in the newly created porous region. I know this has been done before using a similar method (shown below).
Attachment 71171


Although not detailed, from what I gathered the users implemented contact detection which created a porous zone after the proximity threshold was reached. This zone served to obstruct flow in this region, which is exactly what I'm trying to do.

Furthermore, I've seen others use porous zones to block fluid flow as well, although they implemented a UDF to do so (https://youtu.be/Ku-fu_O9WmM)


I can get the contact detection technique to work correctly, however, the porous zone that is created does not obstruct flow as intended. I've already tried changing the porosity coefficient from 1 to 0, which the manual says should have simulated a "solid" zone.
For reference, here is a picture of my porous zone settings:Attachment 71172



Any insight would be greatly appreciated.
