Have you instanciated the base writer clas FemInputWriter? The "NodeLoadTable" should be added there.

Would you point me to a branch where all you code is?
yes, this is my branch:

Re: OpenSees, the Open System for Earthquake Engineering Simulation

I implemented element writer. now, when i want to implement load writer it gives me that error: for ref_shape in femobj["NodeLoadTable"]: KeyError: 'NodeLoadTable' while i copy format from other solver: for femobj in self.force_objects: # femobj --> dict, FreeCAD document object is femobj["Object"] ...

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

ccx has a lot of elements too http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node25.html ATM in FreeCAD FEM there is no object to choose the elment type. If you mesh a mesh with 8-nodes brick, an 8-nodes brick is used in ccx. If you mesh with a prisma element a prisma element is used in ...

opensees has complete element library for structural engineers.

OpenSees commands

can i develop some of them in FreeCAD? specially Beam-column, truss and membrane element? thanks.

for can, i mean ability?! :roll:

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

If you mean in general by the FreeCAD FEM GUI than the answer is no it is not possible ATM. We would need some objects to define these attributes and than the ccx writer would need to be adapted in this regard. bernd thanks. yes, and another thing: define section? I mean another object that can ass...

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

I know we have ElementGeometry1D that give a section type and typical rect, circle, pipe. ElementGeometry2D for shell element.
my question is: how can i define membrane, plate , truss and etc. I don't mean editing .ini file for calculix, i mean in general. thanks
