Building structural design workflow

Postby Walgri » Wed Apr 10, 2019 10:32 am

HI,
I would like to gather information, share points of view and learn how to possibly extend and consolidate the FEM Wb to improve the support for building struttural design workflow.

One of the things I need almost every day is the ability to have mixed 1D and 2D FE meshes, that represent pillars, columns, beams and slabs (on grade or not). AFAIK, only uniform meshed are handled: where is this implemented ? Is this in the C++ o in the Python code ?

Also, it look like no facility is available to connect different meshes at finite element level: we have a single continuous mesh that comes from a single 3d geometry, is this statement correct ?

I am on the way. Just a link ... https://github.com/berndhahnebach/FreeC ... ixedmeshes this enables mixed mesh analysis ... See harrys golden gate bridge :mrgreen: https://forum.freecadweb.org/viewtopic.php?t=27987 based on https://forum.freecadweb.org/viewtopic. ... 9&start=50
