Application ID: 479
This model tracks a contaminant that enters an aquifer at a point, such as an injection well or toxic spill, and spreads through the aquifer with time. The model has an analytic solution developed by Wilson and Miller. This analytic solution has been used to test several dedicated fluid flow and transport codes. The particular problem discussed here comes from the MT3DMS manual of Zheng and Wang.
The analysis is conducted by modeling steady-state fluid flow and following up with a transient solute transport simulation. Furthermore, an adaptive mesh refinement solver is used together with the stationary solver with the resulting mesh perfectly adjusted for calculating the transient transport equation.
This model example illustrates applications of this type that would nominally be built using the following products:Subsurface Flow Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
