1 Short description
Creates a axial-symmetric grid from a two-dimensional grid
2 Usage
Needs two inputs:
- name of the boundary that is the symmetry axis
- name of the boundary that is to be splitted into two wedge-boundaries (front and back)
Assumes the following about the grid:
- 2D-Grid (just one cell thick)
- parallel to the XY-plane
- the boundary that is the symmetry axis is a straight line
- the "front" and "back" are one patch
Afterwards: use the collapseEdges utility to remove the faces at the symmetry axis
3 Example
The original mesh had (amongst others) these faces:
- center
- The face that is to be collapsed an turned into a symmetry axis (at the bottom in the picture on the left)
- frontAndBackPlanes
- The patch that contains the front and the back face and will be split into two patches)
The command
makeAxialMesh . testAxial2 center frontAndBackPlanes
converts this into the mesh seen in the picture on the right.
