Not so clear to me: What is the domain of MTK where using MTK to create models is a good choice?

In particular, we have a package for modelling aerodynamic forces and moments of 3D wings: [GitHub - OpenSourceAWE/VortexStepMethod.jl: Aerodynamic models of 3D wings using the Vortex Step Method](https://github.com/OpenSourceAWE/VortexStepMethod.jl)

Would that be a model that could be re-implemented using MTK at all? If yes, would that be beneficial?

Currently, it uses NonlinearSolve.jl as solver.

Not sure.

Very quick look into the docs tells me that the Vortex Step Method leads is based on the Biot-Savart Law. It therefore leads to dense matrices.

Do packages similar to [BEAST](https://github.com/krcools/BEAST.jl) or [Inti](https://github.com/IntegralEquations/Inti.jl) apply here?

Happy to discuss further.
