Meshing

Generate mesh for solver

The toolbox uses the finite element method (FEM) to solve PDEs. Create a mesh using the generateMesh function. A PDE model stores the generated mesh as an FEMesh object in its Mesh property. For details, see Mesh Data.

Functions

generateMesh Create triangular or tetrahedral mesh
pdemesh Plot PDE mesh
adaptmesh Adaptive 2-D mesh generation and PDE solution
initmesh Create initial 2-D mesh
