Great. Reading from http://www.buildingsmart-tech.org/ifc/I ... smodel.htm
The IfcStructuralAnalysisModel is used to assemble all information needed to represent a structural analysis model. It encompasses certain general properties (such as analysis type), references to all contained structural members, structural supports or connections, as well as loads and the respective load results.
So it is basically a group-like entity, which contains 1) the geometry objects, 2) loads, 3) additional info
I think it maps pretty closely to a FEM analysis object... On opening an IFC file containing an IfcStructuralAnalysisModel, we could create a FEM analysis. the problem I see is that the FEM forces need base objects & faces to be applied to, it will be hard to map these... But I never tried with 1D elements like in ifc analysis curves...
Maybe @bernd will have more insights?
I'm moving this thread to the IFC section.
