The spatial twist continuum is a dual representation of an all hexahedral

Hexahedron

A hexahedron is any polyhedron with six faces, although usually implies the cube as a regular hexahedron with all its faces square, and three squares around each vertex....

 mesh that defines the global connectivity

Connectivity (graph theory)

In mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements which need to be removed to disconnect the remaining nodes from each other. It is closely related to the theory of network flow problems...

Constraint (mathematics)

In mathematics, a constraint is a condition that a solution to an optimization problem must satisfy. There are two types of constraints: equality constraints and inequality constraints...

Discovered by Dr. Peter Murdoch on the 16th September 1993, the spatial twist continuum is a method that can be used in automatic and semi-automatic mesh generation methods to create all hexahedral meshes for both computational fluid dynamics

Computational fluid dynamics

Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with...

The name is derived from the description of the surfaces that define the connectivity of the hexahedral elements.
