comsol_import.m

COMSOL 2D mesh data import, cropping and preprocessing for Spinach.

Syntax

mesh=comsol_import(comsol)

Arguments

comsol.mesh_file - name of an ASCII file with

                      vertex coordinates and edge
                      index produced by COMSOL

   comsol.velo_file - name of an ASCII file with
                      vertex-centred flow veloci-
                      ties produced by COMSOL

   comsol.crop      - {[xmin xmax],[ymin ymax]}
                      region of the mesh to retain

   comsol.inactivate - a vector with mesh vertex
                       indices to deactivate

Outputs

mesh – Spinach mesh object with

                     ▸ geometry (.x, .y, .idx)
                     ▸ flow velocities (.u, .v)
                     ▸ Voronoi tessellation (.vor)
                     ▸ fast-plot auxiliaries (.plot)

Notes

Internally this routine is a convenience wrapper that calls:

   ▸ comsol_mesh()      – mesh import
   ▸ comsol_velo()      – velocity import
   ▸ mesh_crop()        – region trimming
   ▸ mesh_vorn()        – Voronoi tessellation
   ▸ mesh_preplot()     – plotting accelerators
