property Simulation3DElectricField.dt_threshold#

Threshold used when determining the unique time-step lengths.

The number of linear systems that must be factored to solve the forward problem is equal to the number of unique time-step lengths. dt_threshold effectively sets the round-off error when determining the unique time-step lengths used by the simulation.
