An exponential time-differencing method for monotonic relaxation systems
(Journal article; Peer reviewed, 2014)We present first and second-order accurate exponential time differencing methods for a special class of stiff ODEs, denoted as monotonic relaxation ODEs. Some desirable accuracy and robustness properties of our methods are ... -
Numerical treatment of two-phase flow in capillary heterogeneous porous media by finite-volume approximations
(Journal article; Peer reviewed, 2012)This paper examines two-phase flow in porous media with heterogeneous capillary pressure functions. This problem has received very little attention in the literature, and constitutes a challenge for numerical discretization, ...
