The CREATOR Winter School 2024 brought together experts, researchers, and students in order to exchange knowledge and foster collaboration among participants through a mixture of lectures and exercises.

The Winter School started on a Tuesday with three lectures. The lectures “Maxwell equations, conservation laws, interface conditions, formulations, rotating field theory, electromagnetic torques” and “Finite-element method: Ritz- and Petrov-Galerkin methods, convergence, discrete Maxwell equations” were held by Herbert De Gersem. Next followed a lecture about “Modelling of motion, torque calculation, magnetomechanical coupling” by Klaus Roppert.

On Wednesday the following five lectures were held:

• Herbert De Gersem: Linearisation of nonlinear problems: (quasi-)Newton methods, basics of material modelling
• Sebastian Schöps: Time stepping methods, adaptive time stepping, differential-algebraic equations
• Sebastian Schöps: Simulation-based design workflow for electric machines
• Yves Burkhardt: General machine theory, windings, magnetic circuit, rotating field
• Yves Burkhardt: Theory and (semi-)analytic models of induction machines and synchronous machine

The third day of the CREATOR Winter School was dedicated to the following exercises.

• Klaus Roppert: Modelling of hysteresis, parameter identification, introduction in finite-element models
• Christian Kremers: Hands-on simulation of electric machines using Simulia CST Studio Suite
• Klaus Roppert: Speedy Laplace contest (write the fastest 2D FE Laplace solver from scratch)

Friday started with a lecture on “Electromagnetic compatibility in an electric vehicle's drive unit” by Yvonne Späck-Leigsnering and concluded with a lecture on “Uncertainty quantification for electric machines” by Sebastian Schöps.

The CREATOR Winter School 2024 successfully combined theoretical knowledge with practical skills and helped the participants gain a better understanding of relevant topics for their research.
