Help with Solid-Shell connection please
(OP)
Hello,
I thought I finally had a working connection between my solid and my shell area. But the stress results confused me. While investigating I found this:

The grey part is the rendered shell thickness of a pipe. It's using "top surface" for wallthickness assignment. Below the pipe a pipe made of solid-elements is attached.
The upper faces of the connected solid-geometry should also be the faces of shell elements.. For some reason it seems those faces only count as solid elements, therefor no shell-wall-thickness is rendered and you can see through the pipe down to the red solidpipe...can you think of a way to fix that?
Would be very happy about suggestions!

RE: Help with Solid-Shell connection please
but i fail to be able to copy the face at the moment
RE: Help with Solid-Shell connection please
Offset face does not seem to bework below a distance of 0.05.
So I could create an offsetface from the solidface, with a distance of 0.05mm. Then solid-to-shell couple those two faces. And tie constrain the newly offsetcreate-shell-face with the surrounding faces?

I created a smaller version of my problem.
Created a 2d shell face. Extruded a Solid cylinder from the face --> The shell area has god a hole in it when shell thickness is visualized.

To me this seems like the best solution in that case..
if you are very much interested in the stresses at the T-pipe part.. use Solid-Elements and mesh it as one part.
if the you are not very much interested in the stresses, leave shell and solid as two parts, and tie constrain them in the assemble, or use the Edge-to-Face version from the manual instead of face-to-face, as I had in the beginning?
