Creating an internal mesh within blockMesh?
 

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.

Any tips on how I would go about doing this?

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

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.
