Usage of Geometry Primitives

Meshing

In snappyHexMesh, geometry primitives are used to define region refinements. Refer to Hex-dominant parametric: Mesh around a vehicle for an example.

Geometry Primitive types

Box

Cartesian Box

Cartesian boxes are available in several locations at SimScale. Their axes are aligned (parallel) with the global coordinate system. Most notably, they are used - to define mesh refinements in snappyHexMesh and - to define subdomains in multiphase simulations.

Half Space

Sphere

Spheres are available for mesh refinements in snappyHexMesh.

Point

Points are used in Point Data result controls to define the probe point location.

Cylinder

Cylinders are available for mesh refinements in snappyHexMesh.
