********************* Minimum Time Step ********************* :: Minimum time step = ----------------------- Description / Usage ----------------------- This card sets the value of the minimum allowable time step size in a **transient** analysis, a useful control if the time step is being decreased due to poor convergence of the transient or iterative algorithm. The input parameter is defined as Any floating point number in the same units as specified in the *delta_t* card. ------------ Examples ------------ A sample card that sets the minimum time step to 1.e-9 follows: :: Minimum time step = 1.e-9 ------------------------- Technical Discussion ------------------------- This specification provides a graceful way for the program to terminate based on the computed time step dropping below the minimum value rather than terminating by a segmentation fault or a divide-by-zero error that could result if the time step becomes too small without the benefit of this control.
