Simflowny 2: An upgraded platform for scientific modeling and simulation

Simflowny is an open platform for scientific dynamical models which automatically generates parallel code for different simulation frameworks. Here we present major upgrades on this software to support an extended set of model families, in particular: (i) a new family for the evolution of partial differential equations, which can include spatial derivatives of any order, (ii) a new family for agent based models to study complex phenomena — either on a spatial domain or on a graph. Additionally we introduce an upgraded flexible graphical user interface to accommodate these and future families of equations and models. This paper describes the new architecture and summarizes the formal representation and implementation of these new families, providing several validation results.
