URDME

Unstructured Reaction-Diffusion Master Equation

www.urdme.org

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.

URDME 1.4. Copyright 2008--2020

See the file AUTHORS for a complete list of authors.

Quick Start

Download the latest stable release and unpack it, alternatively clone the repository (requires a git client),

$ git clone https://github.com/URDME/urdme.git

To start using URDME under Matlab, navigate to the file startup.m,

>> startup

To run a simple 1D model,

>> cd examples/annihilation
>> annihilation_run

For further instructions, examples and tutorials, consult the software manual,
