Failing to generate tetcore mesh after the generation of boundary mesh.

Hello,

I am trying to mesh a volute region for a CFD simulation. When I am trying to create the mesh the boundary layer is created properly but the tetra-core mesh fails to be generated (so there is just a hollow shell of prism layers). There is also no warning or error messages. Can someone please help me with this issue?

    Sorry about being vague. Here I have attached a picture of the region which is not generating the volume mesh.

    As you can see the prism layer is genrerated. But there is no core mesh.

    Try to make TET volume manually by using faces from layers?

    Thank you. When I use the Boundary layer component to create the faces it creates the faces for the entire boundary layer (ie both inside and outside.of the boundary layer.) Since I need the faces just on the inside of the boundary layer to create the tetmesh I am stuck with having to seperate the faces.i need which is very time consuming. Is there a easy way to create the faces (or extract the faces) just on the inside ?
