simulation_mode - Control the simulation mode of GridLAB-D
The normal simulation mode is the event-based time solver (EVENT). In event-based operation the clock advances in variable time-step of 1 second or more.
The subsecond simulation mode is the finite-difference time solver (DELTA). In delta-based operation the clock advances in fixed time-steps of less than 1 second.
This variable is typically not set via the #DEFINE or command line approach. It is best to let the internal models control the simulation mode.
This capability is introduced in Grizzly (Version 2.3)
