Mathematics of FreeCAD?

It would be beneficial if the mathematics that goes into some module would be available for viewing as well.

Such as, how the rotation in the "scene" is implemented.

Reason:

I think it's easier to have a conceptual explanation than having to read it from the code.

FEM theory in current FreeCAD implementation

What scientific/engineering theory is currently implemented in FreeCAD FEM?
E.g. direct stiffness method.

Re: How approachable is the FEM development if starting from zero?

I have about 3 months of C++ behind now so that shouldn't be that much of a problem. I'm still trying to get my head around the FEM method, but was thinking of perhaps upgrading it to a NURBS based one. Or develop new constructs, in the sense of being able to model things that aren't currently model...

Re: NURBS

Oh yeah correct. The NURBS is merely about changing the fundamental "building blocks" of FEM.

NURBS

So what's the state of NURBS in FreeCAD currently?

There are some papers around that say that NURBS ought to replace FEM.

How approachable is the FEM development if starting from zero?

I have a fairly strong interest in developing the FEM module since I'm specializing professionally in computational (engineering) modelling, but it seems that most commercial CAD packages already have what they need and FreeCAD seems like a better platform because it's open (thus open for experiment...

Re: FreeCAD to incorporate Granta-like features?

The point was that instead of Granta, there could be an open source database that does what Granta does (the same idea). Not that FreeCAD should interface with Granta.

I think it's fairly rational that a materials database ought to be open sourced, because the data is almost universal in a sense.

AFAIK, there's no open source materials database like this?

Re: Feasibility of FreeCAD surpassing Commercial CAD

^If FOSS will ever be an alternative for commercial software development, then it has to surpass it in quality.

Re: Feasibility of FreeCAD surpassing Commercial CAD

Personally, I believe it's just a matter of time. As soon as some key missing functionality (Assembly, CAM) is implemented companies will begin to switch to FreeCAD. Unless they shy FOSS. There's a certain belief that thinks free software is bad and being commercial is required for developing good ...
