Ansys mesh generates only surface mesh but not volume

I am trying to mesh a 3D HEPA Filter geometry. The Ansys mesh only creates mesh on the surfaces but not in the interior of the body. The inside of the body has no mesh at all. Can someone tell me how to solve this problem? Thank you.

Do you have an interior "body" as a solid also? Does this get a check mark when you mesh the entire geometry, to indicate that mesh is finished?

I get the green check mark after mesh is completed but there is no solid body inside it.

Then I guess you must create it prior to meshing?

But i want air to flow inside the body from the empty parts. She is a complicated body so i can't create a solid body inside.

Are you combining solid, porous and fluid domains? In that case you need "solids" for all of them, and they're then defined differently in CFX/Fluent after meshing.

So i can't make the air flow inside if i don't have a solid body inside?

Air will flow in their own "fluid domains". Nothing at all will happen in empty spaces. This is very different from when looking at a geometry in a 3D modelling software.

Then is there a way to fill the geometry? It's a complicated Geiger and it can't be filled with simple fill command in design modeler

This depends on the software. "Volume extract" is one common term. Another way is to use a boolean to subtract a dummy volume from the physical object. Keep in mind that channels and gaps also have to be included, if appropriate.
