Crete Mesher object
When Mesher object is created it takes care of initializing interface to GMSH mesh generator
mesher = mp.Mesher();
Set meshing parameters
mesher.basename ='demosquaremesh'; mesher.folder = '.'; mesher.dim = 2; mesher.clean = false; mesher.quadsonly = false;
Create object describing geometric model to be meshed
geom = mp.geoms.SquareGeom('my_domain', struct('da', 2.0)); % Refine mesh around SE corner by setting lc factor to 0.5 geom.params.lcFactors = [1,0.2,1,1];
Generate geometric model in GMSH geo format.
gmshgeom = mp_geom_rectangle([0,0], [2,1], struct('lc', 0.15));
Generate Mesh object
mesh = mesher.generate(geom, struct('lc', 0.5));
Visualize mesh
The simplest way to visaulize mp_plot_mesh.
figure(1); clf; ghandles = mp_plot_mesh(gca, mesh.nodes, mesh.elements); axis('equal') saveas(gcf, 'demo_square_mesh.png'); % Report demo status mp_manage_demos('report', 'Mesher_square', true);
