In this way (Mesh element dimension = 2D set for meshing) GMSH gives shells, but that are shells on the original solid surfaces. So your model contains something as "double profiles".thschrader wrote: ↑Thu Jan 11, 2018 5:20 pmHi Umberto,
you can use shell elements for FEM-calculation directly generated from the solid.
It is not necessary to extract faces from solid.

It is nice hhassey. But a structural frame should look like this:hhassey wrote: ↑Sat Jan 20, 2018 3:04 amThe structural switch is ready!!!
Thanks to Polaris for her contribution to this.
Just turn the Structural property to True and adjust your parameters as needed
Box= True, The beams form a box otherwise they form an I beam
You can grab a copy of the latest version as always: Here:
Thanks for pointing that out, and taking the time to make a drawing. it seems to me that if you place a beam all along the top of the assembly then the one on top of the window opening is not needed, it is redundant. I am basing the design on the attached paper:
mmmmm. Yes and No. The truth should be "it depends...". A beam only on windows and doors is the minimum structure. It is ok in many cases. But in other circumstances, you should use a top beam along the whole wall. My country (Chile) is a seismic country with a lot of earthquakes. Here, you MUST consider beams and columns for each wall and a reinforcement frame for each opening (windows and doors). Therefore, "it depends...". In this case, It depends on how far you want to go with the features of your macro. I know it is a lot of work. Anyway, thanks for the tool.hhassey wrote: ↑Sat Jan 20, 2018 7:58 pm

Anyways, I will fix the double studs that you mention. and keep the beams as the attached paper shows. I still have a little bug to fix on the box beam, (they should be as wide as the whole frame!)
The ball is rolling!
I guess the macro should be broken down into several macros, i.e. one that does a stud, another a track and so on... so that you can start with the automatic macro and then fine tune your design by hand if needed. I want to make it as real life usable as possible...bitacovir wrote: ↑Sat Jan 20, 2018 10:34 pmmmmmm. Yes and No. The truth should be "it depends...".
