Modia (www.ModiaSim.org) is a set of Julia packages for modeling and simulation of multidomain engineering systems (electrical, 3D mechanical, fluid, etc.). Status and plans of a largely redesigned version of Modia is presented consisting of a new syntax in pure Julia mixing equation with function based modeling (e.g. drive trains + 3D mechanics) and new transformation techniques in order that Modia models can be simulated with the ODE integrators of DifferentialEquations.jl.
