# generate_mesh: mesh generation via matlab for 2D objects
|
|
- Triangular linear elements are generated to describe the mesh.
|
|
|
|
### File structure
|
|
A script *foo.m* generates two files:
|
|
- *foo.txt* : contains
|
|
- number of vertices
|
|
- dimension in space (=2)
|
|
- number of elements
|
|
- number of vertices per element (=3)
|
|
- list of vertex coordinates: x<sub>k</sub>, y<sub>k</sub>
|
|
- list of vertex indices defining the elements: idx<sub>i,1</sub>, idx<sub>i,2</sub>, idx<sub>i,3</sub>
|
|
- **indices start with 1 (Fortran)**
|
|
- *foo_sd.txt* :
|
|
- number of elements
|
|
- subdomain index an element belongs to
|
|
- **indices start with 1 (Fortran)**
|
|
|
|
### current code structure
|
|
- *ascii_write_mesh.m* : function that writes a mesh file for input in other codes
|
|
- *ascii_write_subdomains.m* : function that writes the subdomain number for each element into a file
|
|
- *generate_rectangle_subdomains.m* : function that generates (n x k) subdomains by combining squares
|
|
- *square_4.m* : generates mesh and subdomain files for a square separated into subdomains
|
|
- *rec_kk.m* : generates mesh and subdomain files for kk subdomains
|
|
- *chip_2materials.m* : generates mesh and subdomain files for chip geometry with 2 subdomains
