Application ID: 4410
This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests.
Because the number of observations is smaller than the number of unknown parameters, a geostatistical penalty term is used to discriminate between solutions with comparable fitness values.
The measurement data is generated from a given forward model implemented using the Darcy's Law interface, making it possible to analyze the efficiency and accuracy of the inverse method as well as the optimization solver's performance.
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.
