Meshing

Discretize geometry using triangular or tetrahedral mesh

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.

Programmatic Workflow

Generate Mesh

Adjust a mesh by using additional arguments of the generateMesh function.

Find Mesh Elements and Nodes by Location

Find mesh elements and nodes by their geometric location or proximity to a particular point or node.

Assess Quality of Mesh Elements

Evaluate the shape quality of mesh elements.

PDE Modeler App Workflow

Specify Mesh Parameters in the PDE Modeler App

Interactively specify parameters of the mesh.

Algorithms and Other Theory

Mesh Data

Recommended workflow uses FEMesh objects to represent meshes.

Mesh Data as [p,e,t] Triples

Legacy workflow uses [p,e,t] triples to represent meshes.
