Coupling of existing simulations using bottom-up modeling of choreographies
As a contribution for eScience, we discuss the bottom-up derivation of scientific choreography models from existing simulation workflows interconnected as a multi-scale and multi-field simulation. Starting from a motivating scenario of only implicitly coupled simulation workflows for the studying of thermal aging of ironcopper alloys, we present a choreography life cycle supporting the bottom-up derivation of choreography models and the propagation of changes to the underlying simulation workflows in a round-trip manner. Furthermore, we discuss several distinct starting points for the derivation, namely explicitly and implicitly connected simulation workflow models and already running simulation workflow instances.
