newbiomassCOMETS is a software platform for performing computer simulations of metabolism in spatially structured microbial communities. It is based on stoichiometric modeling of the genome-scale metabolic network of individual microbial species (using dynamic flux balance analysis), and on a discrete approximation of diffusion. For more information, see Harcombe et al., Metabolic Resource Allocation in Individual Microbes Determines Ecosystem Interactions and Spatial Dynamics, Cell Reports, 2014.
