Modeling magnetic field in a power transformer

By Philip Soliman (4945255) and Auke Schaap (4457919).

This is a project for the course WI4204 Advanced Modeling at the TU Delft, in combination with STEDIN Rotterdam. The project is supervised by Domenico Lahaye.

⚠️ Make sure that gmsh is setup correctly if you are using Windows! Follow this guide by dr. Domenico Lahaye. The alternative is to use WSL.

Structure

The project is separated in the following way:

• doc contains relevant (pdf) documents, e.g. Max's Thesis
• mesh contains all the (generated) meshes
• report has the LaTeX files that are used to build the report
• src holds the Julia source code
