This class defines a beam with a circular section.
It can be full or hollow, and its radius and thickness can vary from one end of the beam to the other. The valid parameters for circular beams are:
- "R1" or "R": radius at the first end of the beam.
- "R2" or "R": radius at the other end of the beam.
- "EP1" or "EP" (optional): thickness at the first end of the beam. If not specified or equal to 0, the beam is considered full.
- "EP2" or "EP" (optional): thickness at the other end of the beam. If not specified or equal to 0, the beam is considered full.
See class StructuralElementPart for the description of the other parameters.
