CylinderComponent

Cylindrical component.

The CylinderComponent is a simple ActionComponent which adds a cylinder to the mesh. The user selects the dimensionality of the cylinder using the "dimension" parameter.

• 0D is currently unsupported

• 1D makes the cylinder a simple 1D line, with attributes to keep track of its true radius and volume

• 2D makes the cylinder a rectangle within a local 2D RZ frame of reference

• 3D is not implemented, and would create a 3D cylindrical mesh.

Physics can be created on this component using the "physics" parameter. This parameter accepts a vector of names of Physics. The name of the Physics is generally found in the innermost block. For example, in the snippet below, the diffusion Physics is called added_from_component.

The cylinder component on which the component_with_physics DiffusionCG is active is then created as shown below:
