Welcome to the URDME Webpage.

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

Quick Start

Download the latest stable release and unpack it, alternatively clone the repository (requires a git client). In a terminal type:

$ git clone
$ sudo ./

Consult the software manual in doc/manual.pdf for further instructions, examples and tutorials.
