Hi,
I am new to Cubit and having difficulty getting the mesh to follow the edge of a surface. The surface represents an electrode, and I would like the mesh to have the square outline at the electrodes like the figure below:
Currently, the mesh ignores the square electrodes, and I’d like to know how I can get the mesh to conform to the shape of the electrodes.
My current code is attached below. Any advice would be greatly appreciated!

Hi @MeshMagician,
you need to imprint the surfaces onto the volume.
I modified your journal a bit. It now imprints the surfaces on the volumes and groups your surfaces.
Also i defined a sweep direction to mesh the volume with hexes.
Is this what you are looking for?

Yes, that was very helpful. Thank you!
