Two members of the StochSS team, Brian Drawert and Andreas Hellander, have just released the first version of their spatial stochastic simulation software called PyURDME.
PyURDME 1.0 is a general software framework for modeling and simulation of stochastic reaction-diffusion processes on unstructured, tetrahedral (3D) and triangular (2D) meshes. Unstructured meshes allow for a more flexible handling of complex geometries compared to structured, Cartesian meshes. The current core simulation algorithm is based on the mesoscopic reaction-diffusion master equation (RDME) model.
We plan to integrate PyURDME into StochSS soon !
