Edit Physics Values of Porous Baffle Interfaces - STAR CCM+
 

Hello,

I'm doing a project for university and I'm relatively new to STAR CCM+.
I'm trying to simulate a 2D Filter membrane with a porous Baffle Interface.

For this I need to edit in Interfaces -> [Name of Interface] -> Physics Values -> 'Porous Inertial Resistance' and 'Porous Viscous Resistance'.

The problem is that in my file is no Button where I can go to 'Physics Values'. (See Images)
I know that it is possible because a colleague of me (that I cannot ask at the moment) already did this.

What am I doing wrong?
Maybe it is not a big problem but I'm trying to solve this for several hours and I have not found any solutions in the internet.

I'm very thankful for any answers.

Simon

The Problem was that I had no Physic-Continuum.
