Geometry and mesh of the block with cylindrical hole
This construction shows the RBE3 constraint. This is used to apply a moment to the top surface of a cylinder. The bottom surface of the cylinder is fixed 3dof to the world. The inner and outer diameters of the cylinder are 15 and 17 (arbitrairy units) and length 75. The used material is steel, material properties are in ISO units (this makes the dimensions of the cylinder ISO as well).
The geometrical entities on the cylinder are, A for surface areas:
- Atop and
- Abot
Abot is used to apply the torsion moment, Atop is used to apply the fixed boundary condition to the 'world'.
Some images of the construction:
