Seepage modeling remains a crucial numerical analysis commonly performed by geotechnical engineers. The needs of the industry have required on-going research in the area of seepage modeling. Comprehensive solution of groundwater seepage has required the evaluation of multiple solvers for the seepage equation. Such multiple solvers require extensive benchmarking efforts to prove performance both in terms of accuracy and speed of solution. Benchmarking must proceed in terms of steady-state as well as transient problems in 1-D, 2-D, and 3-D. Mesh density and solution time in transient seepage models must be optimized. This paper examines the ability of SVFLUX GT to solve a suite of benchmarks for saturated/unsaturated groundwater seepage numerical modeling.
