Specifies the (
) parameter in the
generalized trapezoid time integration algorithm. The default is 1,
which provides a first order accurate (in time), A-stable, and
L-stable algorithm. Due to the temporal stiffness of the equations
and the fact that usually large time steps are taken, it is not
recommended that the default is changed. Any value other than 1
removes the L-stable property, and damped oscillations may appear in
the solution.
