We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I agree they are quite high ????. However, the three domains are porous domains, so, I have (from the left to the right):

CellRegion 1 and 3: 

porosity = 0.38

liquid phase:

         perm(x,y,z) = 1.216e-10

gas phase:

         perm(x,y,z) = 1.216e-10

 

 

CellRegion 2: 

porosity = 0.53

liquid phase:

      perm(x) = 1.216e-10

      perm(y,z) = 1.216e+14 

gas phase: 

    perm(x,y,z) = 1.216e+14 

 

My goal is that the liquid can only pass the centered domain on the x-direction and no gas can pass from the sides to the center, so that the centered domain would be impermeable to gases. 

Am I thinking correctly or would you define differently? 

 

Thank you for your inputs btw!!!
