Sets the time-dependent state of the operator. This version of setTime allows one to linearly interpolate coefficients across an integration step, since it accepts arguments that define where in the step it is to be updated. The default implementation calls setTime(a_oldTime + a_mu * a_dt).
a_oldTime | The time at the beginning of the current step. |
a_mu | The fraction of the current step that has elapsed. |
a_dt | The size of the current step. |
