We are likely to need a more advanced modeling tool in areas such as thermodynamics, mechanics, fluid dynamics, chemistry, transportation, construction, and physics in general. MATLAB or Simulink are the most common commercial software available, but other open source technologies such as OpenModelica (https://www.openmodelica.org/), SageMath (http://www.sagemath.org/), or GNU Octave (https://www.gnu.org/software/octave/) can be considered as well. OpenModelica, in particular, supports a Python API, so the physics-based model can be built by an expert with OpenModelica and we can then decide to integrate the model in our analytics at a later date.
