Re: OpenSees, the Open System for Earthquake Engineering Simulation

I am totally with you. Something between Arch (BIM) and FEM. Something which uses the Arch structural nodes and makes in put of loads an load combinations very easy. There is just one little problem with this. TIME ... I have this in mind for years, but never started to do some serious code in this...

new workbench for structural engineers

Hello, as discuss here , i think we must create new WB that inherit some property from FEM and BIM WB to suite for structural engineering. for example in structural analysis we assume Z direction to be gravity load, only 1D and 2D elements and so on. I think we must create new objects that inherits ...

Re: FEM documentation missing on the Wiki

@Kunda1, @bernd. is it possible to use readthedocs for documenting. i see most of the software use that for documentation, like ezdxf library, this one and this.

i think we must provide a good API document for FEM WB

Re: OpenSees, the Open System for Earthquake Engineering Simulation

see this https://github.com/FreeCAD/FreeCAD/blob/da92b8c242ead8cc106f480aa2eed0bac2edf10a/src/Mod/Fem/femsolver/writerbase.py#L405 In ccx writer I had to get these local rotations too. thanks, you mean i must assign Elementrotation1D to each beam or column or a bunch of those? @bernd, i think if we...

Re: OpenSees, the Open System for Earthquake Engineering Simulation

@bernd. I analysed this model successfully with opensees. but still i can't assign proper section to each element, can you please tell me?

Re: OpenSees, the Open System for Earthquake Engineering Simulation

In continues this post , also for defining transformation in OpenSees i need to know which element has which direction to assign proper section properties to it. thanks. https://opensees.berkeley.edu/wiki/index.php/Linear_Transformation https://opensees.berkeley.edu/wiki/images/5/5e/ElementOrientati...

z88 does support it, but FreeCAD Z88 writer not.
Exactly i mean this. ;)

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

How can i recognize which 1D section element is for which element? i have two beam_section object: self.beamsection_objects = [{'Object': <Fem::FeaturePython object>, 'RefShapeType': 'Edge'}, {'Object': <Fem::FeaturePython object>, 'RefShapeType': 'Edge'}] i think i can obtain it, but a little compl...
