I will be using investigating the opportunities that Extempore provides in creating a more dynamic workflow for scientists programming simulation and how Extempore can be used to make these simulations more powerful. With the help of some C++ fluid dynamics code, I will be exploring the best ways to use Extempore to create a more effective environment for scientific simulation while doing some real physics. It will show off how extempore can be used to change non-trivial aspects of a simulation at run time.
