Multiphase porous media model:inertial and viscous resistance button doesn't show up
 

Hi all,

I am trying to model a 2D porous zone filled with sand placed above a perforated pipe and water will pass through it. I am facing a weird problem. When I active multiphase flow, input button for rotation axis direction,inertial resistance and viscous resistance simply disappears!! only porosity parameter remains active. I tried with 3D also, same case happened. But I need to model multiphase flow. What should I do ? Thanks a million in advance.

By the sounds of it you are looking in the "Mixture" Phase. This is in a dropdown box below the "Zone" panel. Go to the dropdown box and select one of the phases. You will find that all the missing parameters will appear here. Essentially you can set different parameters per phase

Hi Swiftaircraft, Thanks for your reply. I have already tried what you are saying, but unfortunately, for each phase these parameter is not active. Please see the attached image. Please let me know if you have any other idea about it. Thanks a lot again for your reply.

Hi Swiftaircraft,

I have found something. I have to define porosity from mixture phase. And for which zone I defined porosity, I can assign viscous and inertia resistance for that phase which I assigned in porous zone. For example, I named one zone as water. I defined water zone as porous zone from mixture phase, then I can assign other permeable parameter for water zone by selecting phase-2 ( I assigned water as phase 2). Did you mean this way ? Please let me know. And thanks a lot for the idea.
