Stochastic reaction-diffusion simulation on unstructured meshes.


Unstructured Reaction-Diffusion Master Equation

URDME is a general software framework for modeling and simulation of stochastic reaction-diffusion processes on arbitrary meshes. URDME emphasizes modularity in order to be useful both as a simulation tool and as a framework for development of stochastic simulation algorithms.
