Combine simulations @Vivarium! We’re in the BioSimulators pipeline: https://biosimulators.org. BioSimulators is a free registry of biosimulation tools, with a standardized interface. The simulators support a broad range of frameworks (e.g., logical, kinetic), simulation algorithms (e.g., FBA, SSA), and formats (e.g., BNGL, CellML, NeuroML/LEMS, SBML, Smoldyn). And with Vivarium, they can now be combined to create novel multi-scale simulations.
