Re: GSoC Proposal: Extended functionality of Rebar Addon

See screenshots. bbs101.png BBS102.png Added above Bar Bending Schedule image (BBS102.png) as expected output for bar bending schedule in proposal. there is another example in one of your posts. It is similar to the one you added. https://forum.freecadweb.org/viewtopic.php?f=8&t=44580#p381124

Re: GSOC 2020 has been Green Lit! (Voice your opinion and ideas about what to propose for the next gsoc)

Hey, Sorry for being so late to the party! I would have some idea in FEM ... Extend the examples. This is easy to do for someone with a bit knowledge of FEM and Python. No deeper knowledge o FreeCAD FEM is needed. See https://github.com/FreeCAD/FreeCAD/tree/39b691a994e8815fd9181baa7d10bc06e0111673/...

GSoC2020, FEM: extend examples

the deadline for Student application is just in a few days ... As a result of a discussion there came up an idea for a 2020 GSoC. Extend the FEM examples. - create a example for each available constraint and each available analysis type or equation type - take some of well known fea examples like th...

Re: 1/2D element like membrane, plate, truss?

4 nodes means first order elements without middle node ...

- set gmsh mesh object attribute ElementOrder to 1st
- use min element size 5000 mm

Re: Blender now supports IFC export

FreeCAD really has per design problems on huge modells with ten thousands of objects in the TreeView.

@moult:
Do you use BlenderBIM as your standard IFC viewer as well?

Re: Blender now supports IFC export

wow

lots of cool useful features!

@moult do you use the code made in a FreeCAD GSoC to parse IFC ? If yes how does it works? It not much used by FreeCAD users ATM.

Re: Collecting face elements from surfaces with gmsh (getFacesByFace)

ahh 1.8 M which is a lot but it should not take hours but it can take long ... All the geometry mesh seach tools are not optimised on cost thus on huge meshes really take very long.

Re: Collecting face elements from surfaces with gmsh (getFacesByFace)

I am on a mobile and thus can not test ATM. What I would do is create mesh group objects in FreeCAD FEM. They are childs of the gmsh mesh object. With them the group geometry will passed to gmsh. Gmsh than returns the mesh with the groups included. This is not much slower than just meshing. BTW. How...
