Detailed Description

template<class TAlgebra>
class ug::LinearImplicitEuler< TAlgebra >

This time stepping scheme discretizes equations of the form

\[ M \partial_t u(t) = f(t) \]

as

\[ (M - \Delta t J) \left( u(t^{k+1}) - u(t^k) \right) = \Delta t \cdot f(t^{k}) \]

Thus, for $\theta = 1 $ this is the Backward-Euler time stepping.
