Very interesting, making simulations "easy and accessible" really resonates with me having spent far too many years single handedly trying to get traction for my "easy to use" engineering physics, FEA, and PDE ideas and simulation tools [1]. I would be very interested in collaborations if anyone from hash.ai (or anyone else) is reading this and ever think of including/or moving in to the "easy to use" PDE based simulation space.
