Abstract
The addition of a mobility model to a finite-element simulator was found to create a convergence problem identified with the addition of positive terms to the off-diagonal elements in the solution matrix. Fast convergence rates were recovered by carefully adjusting the solution matrix such that the off-diagonal elements in question were all nonpositive
