Detailed Description
Convergence criterion which looks at the absolute value of the residual and fails if the linear solver stagnates.
For the CombinedCriterion, the error of the solution is defined as
![\[ e^k = \max_i\{
\left| r^k_i \right| \}\;, \]](form_123.png)
where 
is the residual for the k-th iterative solution vector 
.
In addition, to the reduction of the maximum residual, the linear solver is aborted early if the residual goes below or above absolute limits.
