  The Durham Adaptive Optics Simulation Platform (DASP) is a Monte-Carlo
modelling tool used for the simulation of astronomical and solar adaptive
optics systems. In recent years, this tool has been used to predict the
expected performance of the forthcoming extremely large telescope adaptive
optics systems, and has seen the addition of several modules with new features,
including Fresnel optics propagation and extended object wavefront sensing.
Here, we provide an overview of the features of DASP and the situations in
which it can be used. Additionally, the user tools for configuration and
control are described.
