A means of solving ordinary and partial differential equations. The domain of the problem is broken up into elements, and the solution in each element is expanded in a basis of functions. The Finite Element Method lends itself well to adaptive refinement, irregular geometry, and good error estimates.

Defining Current Density in a FEM model (MATLAB)
Defining current density in this system can be done by considering the average current density within the winding region, $J_{0}$ (then subdividing this into elements). For winding height h, Inner cro …

Create mesh for complicated 3D object for finite element analysis
A quick note on the .stl for 3D modelling:
As noted in the documentation here (Limitations at the bottom) for 3D models MATLAB cannot recognise multi-domains from 3D STL files. If two objects share c …

Defining Current Density in a FEM model (MATLAB)
I'm attempting to solve the Poisson equation in 3D for a magnetic vector potential in the presence of a current source. To validate my code, I'm initially looking to reproduce the model described in t …

Multi-domain 3D Geometries for MATLAB PDE Toolbox
In principle the PDE Toolbox in MATLAB can handle multi-domain 3D geometries as noted here.
This feature and the associated function geometryfromMesh were introduced in MATLAB R2018a. The associated …
