Simulation

A simulation in Lumol always contains the same steps:

1. Setup the system and initialize the algorithms using system specific information;
2. Propagate the system for one step using a Propagator;
3. Compute the physical properties of the system and output them to a file;
4. Check if the simulation is finished (either the required number of steps has been done, or a convergence criterion is reached) and return the updated system. If the simulation is not finished, go back to (2)

Propagators

Propagators are at the heart of a Simulation. They have the responsibility to update the system at each simulation step. Currently, three propagators exists: a molecular dynamics one, a Monte Carlo one and a minimizer, for energy minimization.

Output algorithms

Output algorithms have the responsibility to compute and output statistical data about the simulated system. Temperature, energy, radial distribution functions are some examples of output algorithms.
