MATLAB: Convert [p,e,t] to FEMesh for PDEModel

meshpde

Hello

I want to import a mesh defined by [p,e,t] into a PDEModel. I know I can generate a mesh by generateMesh, but the thing is, that I want to refine the mesh in certain/specified regions of my geometry. This is not possible with generateMesh. Thank you in advance for any help. LF

Sorry, there are currently just three ways to create 2-D geometry, and getting geometry from a mesh isn't one of them.

MATLAB: How to create a 3D mesh

Use the "generateMesh" function in the Partial Differential Equation Toolbox to generate a 3D mesh.

Refer to the following example that imports a 3D model, creates a mesh, and displays the mesh.

model = createpde;
importGeometry(model,'Torus.stl');
mesh = generateMesh(model);
[p,e,t] = meshToPet(mesh); %convert form of mesh
figure; pdemesh(mesh);
figure; pdemesh(p,e,t);

MATLAB: Applying Nonconstant Boundary Conditions for pde

The pdeGeometryFromEdges function is part of a new, simpler approach to defining boundary conditions in PDE Toolbox introduced in R2014b.

If you want to define boundary conditions programmatically (as opposed to using the pdetool GUI) in R2014a or earlier versions of PDE Toolbox, you will need to write a boundary condition function. This documentation page:

http://www.mathworks.com/help/pde/ug/pdebound.html

describes that in more detail. The links at the bottom of that page will take you to documentation pages with examples.
