However, the geometric multiplicity can never exceed the algebraic multiplicity . 0000002323 00000 n 0000002345 00000 n The phenomenon being modeled is a sequence of independent trials. geometric modeling forms 1.1 Motivation Geometric modeling deals with the mathematical representation of curves, surfaces, and solids necessary in the deﬁnition of complex physical or engineering objects. Solid model • Solid modeling is based on complete, valid and unambiguous geometric representation of physical object. This medial modeling concept developed at the Welfenlab yields a very intuitive user interface (UI) useful for solid modeling, and also gives as a by‐product a natural meshing of the solid for FEM computations. 2. 0000004920 00000 n •The design process greatly benefits from allowing Non manifold models (hybrid solid, surfaces, and wireframes). There are only two possible outcomes for each trial, often designated success or failure.
