I am now using Modelica with OpenModelica at work to describe electromagnetic systems and it is an excellent language and, with OpenModelica, a excellent graphical user environment. Sometimes I think of it like SPICE but for multi-physics systems.

The Modelica library is quite mature and complete and the numerical solvers included with OpenModelica robust and performing.

It looks me a while to learn it but now it is paying out.

In addition the fact that Modelica is a standard implemented by several suppliers with an open source application is also great to avoid vendor lock in so that is a technology on which is safe to invest as an engineer and as a company.

Modelica is an excellent way to perform these simulations. Exporting a functional mock-up unit (FMU) according to the FMI standard is a first-class capability [1] that is another huge source of value, especially for systems integrators. You are able to have reasonably obfuscated models of your system in untrusted hands, and they get the full benefit of your system model. This is one area where OpenModelica is ahead of competitors including the open-source ModelingToolkit.jl [2] and related library FMIExport.jl [3].

I remember using OpenModellica to test an Functional Mockup Unit where I extracted Neural Net as ONNX and the ONNX runtime DLL and then connected it to Simcenter Amesim as my student work at Siemens. Pretty okay standard compared to how old and crusty the APIs of engineering software are.
