SVFlux - 2D Gallery - Geomembrane Problems



Solution of a problem involving extreme geometry variation. A fine, almost impermeable geomembrane is placed between the landfill material and the regional soil. Significant mesh refinement is encountered to accommodate the large changes in permeability over a small spacial distance but the problem solves in reasonable time.

Geomembrane Complex


The problem involves the modeling of a thin geomembrane liner underneath fill. This problem demonstrates the ability of the software to solve extreme differences in hydraulic conductivity and geometry. The problem width is approximately 100m and the thickness of the geomembrane is set at 1 cm. The geomembrane is described at the top of the tan colored sand layer and is not visible at the scale shown above.
