Bases: ShapedComponent

A RadialSegement represents a volume element with thicknesses in the azimuthal, radial and axial directions.

This a 3D projection of a 2D shape that is an angular slice of a ring or circle.

The 2D shape is like the one below, with an inner and outer position for the theta and the radius:

This component class represents a volume element with thicknesses in the azimuthal, radial and axial directions. Furthermore it has dependent dimensions: (outer theta, outer radius, outer axial) that can be updated depending on the ‘differential’ in the corresponding directions.

This component class is super useful for defining ThRZ reactors and perturbing its dimensions using the optimization modules
