Use Simulation Time in Equations

You can access global simulation time from the equation section using the time function. time returns the simulation time in seconds.

The following example illustrates y = sin (ωt), where t is simulation time:

component
  parameters
    w = { 1, '1/s' } % omega
  end
  outputs
    y = 0;
  end
  equations
    y == sin( w * time );
  end
end
