IFC for steel connection modelling
We are developing some Python tools to automate the creation of 3D finite element models (using CBFEM to make meshing easier) in XC.
We have a decent solution for creating the finite element mesh from the block topology information (the points, lines and surfaces that define the domain to mesh like in Ansys or in Gmsh) but we are reinventing the wheel with the code that generates those blocks: we are using a quite dirty solution to express things like: this weld connects gusset plate A with column B top flange or this hole belongs to the plate C.
I imagine that IFC has already mechanisms to express the geometry of the different elements and the relationships between them. Could you point us to the right documents or examples we can use to understand how to do this?
