Performance Tips
While the default ModelingTolkit backend is highly capable, it doesn't scale well to very large systems of ODEs, present iun high resolution and/or higher dimensional PDE semidiscretizations that MethodOfLines.jl is capable of generating.
To overcome this limitation, and scale MOL to realistic physics simulations, JuliaHub Inc. has released JuliaSimCompiler.jl (installation instructions here).
Whenever this package and MethodOfLines are loaded together, MOL will also load MethodOfLinesJuliaSimCompilerExt.jl, an extension that takes advantage of this backend to speed up your compilation and solves automatically, with the same interface you are used to.
