Detailed Description

Time state management for simulation time integration.

This file defines the Time class, which manages the temporal state of simulations in OpenPFC. The Time class tracks:

• Start time (t0), end time (t1), and time step (dt)
• Current simulation time and increment counter
• Save interval (saveat) for output scheduling

The Time class provides queries for:

• Current time: get_time()
• Time step: get_dt()
• Completion status: is_done()
• Save scheduling: is_save_step()

Typical usage:

// Define simulation time parameters
pfc::Time time({0.0, 100.0, 0.1}, 1.0);  // t0=0, t1=100, dt=0.1, saveat=1.0
 
// Time integration loop
while (!time.is_done()) {
    model.step(time.get_dt());
 
    if (time.is_save_step()) {
        write_results(time.get_time());
    }
 
    time.increment();  // Advances time by dt
}

This file is part of the Simulation Control module, managing temporal aspects of time-dependent simulations.
