Mesh density control demo

Illustrate meshing LShapeGeom with various mesh densities

The LShapeGeom class provides convenient object oriented interface for managing L-shape geometry model.

clear variables;

When Mesher object is created it takes care of initializing interface to GMSH mesh generator

mesher = mp.Mesher();

mesher.basename ='demolshape';
mesher.folder = '.';
mesher.dim = 2;
mesher.clean = true;
mesher.quadsonly = false;

geom = mp.geoms.LShapeGeom('my_domain');
geom.params.dW = 3;
geom.params.dt = 1.2;

mesh_coarse = mesher.generate(geom, struct('lc', 0.8));

The simplest way to visualize mesh is to use Viewer class.

viewer = mp.Viewer();

viewer.show(mesh_coarse);

Generate and visualize mesh again.

mesh_fine = mesher.generate(geom, struct('lc', 0.2));

viewer.stackFigure();
viewer.show(mesh_fine);
