The SkeletonCAD Technology
The MAR™ enables to perform finite element simulations directly on the same model and to store the results in a seamless manner. The simulation results, in particular the deformed shape is fully recovered and can be used for evaluation or for consequent operations including simulations.
As of the current state-of-art in CAD, a 3D object is represented by a closed graph of the outer faces. Although it encloses a volume, it is a boundary-type of representation and not a volumetric one, therefore subject to many limitations.
Medial Axis Representation
Medial Axis (or the skeleton) is the geometric location of maximum spheres inscribed in a 3D object. By adding a radius function defined along the Medial Axis, the resulting Medial Axis Representation™ (MAR™) defines a volume.
The MAR™ introduces the notion of thickness across the solid and provides an interior connection between the boundary elements. So called “wing edges” define the sharp corners, while the rest of the elements can be further classified function of their topological relevancy.
The same object for the user
The MAR™ is used for reasoning. The boundary elements are kept on the skeleton structure, allowing the user to work with the same comfortable Boundary type of representation. At least for the time being…
The MAR™ enables quite a few novel functions. Pictured here is the ability to deform solid objects, using realistic FEM-based simulation. The deformed shape is a valid CAD model with both MAR™ and Boundary Representation, having the same topology as the original.
What is MAR™?
