Hi,

Do you know if there is a way in order to draw attached geometries in COMSOL?

Or any idea if I am able to create a concave workplane?

Thanks in advance.

This is not very elegant, but will this do? If you don't have version 5.0, this is the procedure:

1. Create a hollow cylinder and cut it with, e.g. blocks to a desired shape.
2. Draw another block across this tubular wall.
3. Partition the last block.
4. Convert this partition to curves.
5. Remove extra edges.

As an alternative to Lasse's approach:
Since it looks like you have a CAD software, you could import the geometry using the COMSOL CAD Import Module, rather than redrawing the geometry using COMSOL's own drawing tools. The CAD Import Module supports a wide range of formats, including Parasolid, step, sat, IGS, as well as the native formats of a number of common CAD programs (See www.comsol.com/products/specifications/cad/ for more details).
Best,
Jeff

Thank you very much for your help. Actually I have already tried what you mentioned however I have stuck when I was trying to draw mounted concentric cylinders which are mounted on the concave surface. Do you have any idea if I can draw those cylinders too?

Thank you very much for your advise. I have already tried to Import my CAD file as well. However I have got some geometry issues. So my simulation didn't work properly. I think the attachment explains my problem much better.
Do you have any suggestion for this problem?
Thank you.
