FEM – Water Flow brukes til å utføre “steady state” tilstand eller “Transient” vannstrømningsanalyse (seepage). Gitt materialegenskapene og startbetingelsene ved modellgrensene, beregner programmet utviklingen og stabil tilstand for poretrykkfordelingen, metningsgraden i den umettede sonen, “seepage” hastigheter og innstrømning / utstrømning gjennom modellen. Det resulterende grunnvannstabellen kan importeres til standard spenning-tøyningsanalyse.

Water Flow er en utvidelsesmodul for FEM-programmet for analyse av generelle geotekniske problemer.
