- property BaseTDEMSimulation.time_steps#
Time step lengths, in seconds, for the time domain simulation.
There are two ways in which the user can set the
time_steps
property for the forward simulation. The most basic approach is to use a(n_steps, )
numpy.ndarray
that explicitly defines the step lengths in order. I.e.:>>> sim.time_steps = np.r_[1e-6, 1e-6, 1e-6, 1e-5, 1e-5, 1e-4, 1e-4]
We can define also define the step lengths in compact for when the same step length is reused multiple times in succession. In this case, the
time_steps
property is set using alist
oftuple
. Eachtuple
contains the step length and number of times that step is repeated. The time stepping defined above can be set equivalently with:>>> sim.time_steps = [(1e-6, 3), (1e-5, 2), (1e-4, 2)]
When set, the
discretize.utils.unpack_widths()
utility is used to convert thelist
oftuple
to its(n_steps, )
numpy.ndarray
representation.- Returns:
- (
n_steps
, )numpy.ndarray
The time step lengths for the time domain simulation.
