I have a problem in visualization all mesh regions in para view. As you can see I have defined all parts of my case in SnappyHexMeshDict file both in geometry and refinementSurfaces :
geometry
{
media-1.stl
{
type triSurfaceMesh;
name media-1;
}
media-2.stl
{
type triSurfaceMesh;
name media-2;
}
media-3.stl
{
type triSurfaceMesh;
name media-3;
}
media-4.stl
{
type triSurfaceMesh;
name media-4;
}
media-5.stl
{
type triSurfaceMesh;
name media-5;
}
media-6.stl
{
type triSurfaceMesh;
name media-6;
}
media-7.stl
{
type triSurfaceMesh;
name media-7;
}
media-8.stl
{
type triSurfaceMesh;
name media-8;
}
frame.stl
{
type triSurfaceMesh;
name frame;
}

refinementBox
{
type searchableBox;
min (-300 -300 -300);
max ( 3000 300 300);
}
};

PROBLEM is that Paraview does not show these parts and only shows boundaries that is defined in BlockMeshDict. How can I solve the problem?
Thank you,
