How do execution times of MODFLOWT compare with other transport models?
One of the principal advantages of MODFLOWT is its execution speed compared to other popular transport models. In benchmark tests against MT3D96, MODFLOWT was shown to range from two to 20 times faster depending on the nature of the problem. This is particularly true for simulations with complex geology comprised of variable-layer elevation and thicknesses. The new ORTHOMIN solver in MODFLOWT offers significant advantages over the traditional Slice Successive Overrelaxation (SSOR) solver without sacrificing numerical stability or accuracy.
