Clock

The clock tracks simulation step and time, and defines the integration time step.

Example:

local clock = require("halmd.mdsim.clock")
clock.on_set_timestep(function(timestep)
    print(("time step has changed to %g"):format(timestep))
end)
halmd.mdsim.clock.step

Current simulation step.

halmd.mdsim.clock.time

Current simulation time in MD units.

halmd.mdsim.clock.timestep

Integration time step in MD units.

halmd.mdsim.clock.set_timestep(timestep)

Define integration time step.

The value of the time step is propagated to all integrators.

halmd.mdsim.clock.on_set_timestep(slot)

Connect a unary slot that accepts the integration time step.

This slot is called after setting the time step with set_timestep().
