Geometry and mesh of the block with cylindrical hole
This construction shows the use of LIAISON_DDL to simulate boundary condition on a cylindrical hole. It just shows the use of it.
The boundary conditions ore build around a cylindrical hole in a block. The nodes attached to the cylinder are restricted to rotate around its central axis. The definition of this axis is done by two points P1 and P2 that need to be provided.
The geometry consists of a block with a cylindrical hole near the bottom side. The overall dimensions of the block are [Lx * Ly * Lz] = [2.0 * 3.5 * 20.0 ]. The hole is placed on the x-plane at position [yc, zc] = [2.0, 3.0]. The radius of the hole is R=0.45.
Some images of the construction:
A number of groups has been defined (P for plane, L for line segments):
- Ptop (not used)
- Pbot (not used)
- Pcyl (could be used to define nodes on this surface)
- Lcyl (not used in final version) and
- Ltop, used to apply boundary conditions in x and y direction.
