porosity is not restricted in porous zone

Hi all,

I am doing a transient simulation with UDS and many source term UDFs. I met a problem which confuses me so much. I have two porous zones in the model and porosity is calculated by some equations. I use a UDM to store porosity values.

When I checked contour of porosity, I found porosity existed in some non-porous zones. It's definitely unreasonable. I put the porosity contour below. Can anyone give me some suggestions?

Best
