Hi,

I would like to create an internal mesh (cylinder) within a blockMesh (cube).

The idea would be to import a cylinder into the cube geometry. The end result would merge both the geometries together. However, I require that the cylinder maintains its surface patch after the merging.

How should I go about doing this?

Hi!

Try to use snappyHexMesh. I think that's the easiest way.

Under refinement surfaces in snappyHexMesh, there is option to provide faceType as internal

Quote:
refinementSurfaces
{
shape_name
{
level (2 2);
faceType internal;
faceZone shape_name;
cellzone shape_name;
cellZoneInside inside;
}
}
Here shape_name is specified in the geometry section. For more information, read the snappyHexMesh dict file from the directory etc/caseDicts/annotated

Thanks sk11 ! Turns out in 2 days I figured out the same thing as well and learnt how to use SHM as well Patience is key

I'm using the baffle option though instead of internal it seems to do the job for my small test cases.
