-alpha value

Specifies the tex2html_wrap_inline777 ( tex2html_wrap_inline779 ) 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.
