TimePeriod
The TimePeriod class derives from ConditionalEnableControl.
TimePeriod objects are designed to control the active state of a MOOSE object, based on whether the time value is in some range.
For example, consider a simulation that contains two Kernels "diff0" and "diff1". Initially, "diff0" is active and after time 0.49 "diff1" becomes active and "diff0" is disabled. The following code snippet demonstrates how this switching of kernels is achieved with the TimePeriod object.

# This test is to ensure that the smeared cracking model correctly handles finite
# rotation of cracked elements.
# This consists of a single element that is first subjected to tensile loading
# in the y-direction via a prescribed displacement. This loading is sufficiently
# high to crack the material in that direction, but not completely unload. The
# prescribed displacement is then reversed so that the element is returned to its
# original configuration.
# In the next phase of the analysis, this element is then rotated 90 degrees by
# prescribing the displacement of the bottom of the element. The prescribed
# displacement BC used to crack the element in the first phase is deactivated.
# Once the element is fully rotated, a new BC is activated on what was originally
# the top surface (but is now the surface on the right hand side) to pull in
# the x-direction.
# If everything is working correctly, the model should re-load on the original
# crack (which should be rotated along with the elemnent) up to the peak stress
# in the first phase of the analysis, and then continue the unloading process
# as the crack strains continue to increase. Throughout this analysis, there should
# only be a single crack, as manifested in the crack_flags variables.

# There are 2 scalar variables, {u, v}, with the ODEs:
# du/dt = 1 u(0) = 0
# v = u v(0) = -10
# A control switches the ODE 'v = u' to the following ODE when t >= 2:
# dv/dt = 2
#
# 5 time steps (of size dt = 1) will be taken, and the predicted values are as follows:

# One 3D element under ramped displacement loading.
#
# loading in z direction:
# time : 0.0 0.1 0.2 0.3
# disp : 0.0 0.0 -0.01 -0.01
# Gravity is applied in y direction. To equilibrate the system
# under gravity, a static analysis is run in the first time step
# by turning off the inertial terms. (see controls block and
# DynamicTensorMechanics block).
# Result: The displacement at the top node in the z direction should match
# the prescribed displacement. Also, the z acceleration should
# be two triangular pulses, one peaking at 0.1 and another peaking at
# 0.2.
# The y displacement would be offset by the gravity displacement.
# Also the y acceleration and velocity should be zero until the loading in
# the z direction starts (i.e, until 0.1s)
# Note: The time step used in the displacement data file should match
# the simulation time step (dt and dtmin in the Executioner block).
