Summary0003932: FEM - Selecting the interior solids of CompSolid
DescriptionI'm going to simulate composite materials but I've come across with inability to select the interior solids of CompSolid.

This problem arises when asigning mesh region and/or material to the interior solid.

Adding a clipping plane to see the interior shapes and selecting either the edge or the face that belong to the interior solid yields a message "Edge (Face) belongs to more than one solid".

I was following this tutorial.

OS: Windows 10
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.16274 (Git)
Build type: Release
Branch: master
Hash: 7c760259a389b38b76da78e4f6e1f9be66714842
Python version: 2.7.14
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.2.0
Locale: Russian/RussianFederation (ru_RU)
Steps To ReproduceFEM Workbench. Analysis is activated.

0. Create a clipping plane via Utilities -> Clipping plane on face to see the interior
1. Highlight the CompSolid in the tree view
2. Select Mesh -> FEM mesh form shape by Gmsh and then leave the dialog by clicking OK button
3. Highlight FEMMeshGmsh in the tree view and create a Mesh Region via Mesh -> FEM mesh region
4. Enter max element size
5. Toggle the selection mode to Solid and press "Add" button
6.1. In 3D view select edge/face that belongs to the interior solid
6.2. Use SelectingTools and select any solid in the list
Additional InformationI think the feature of selecting the interior solids must be.

How I see this feature. When selecting vertext/edge/face of the interior solid somewhat context menu or window with contiguous shapes listed comes up. There shoud be edges, faces or solids corresponding to the selection mode chosen. Hovering on the item of the list makes this item highlighted in 3D view. Selecting the solid in the list adds it correctly to the list of mesh region/material assignment.

The similar functionality is implemented here but selecting the interior solid form the list yields an error in the Report view.

Fixed typo in title.
@AndreiTsayukov thanks for the well written report. In the future please first post to the FEM forum to get the FEM core devs attention as we suggest in the guidelines posted in the yellow banner at the top of this page.
Bernd, assigning to you so you see this.
