Variably Saturated Flow
This example utilizes the Richards’ Equation interface to assess how well geophysical irrigation sensors see the true level of fluid saturation in variably saturated soils. The challenge to characterizing fluid movement in variably saturated porous media lies primarily in the need to ... Читать дальше
Aquifer Water Table Calculation
This model demonstrates the application of COMSOL Multiphysics to a benchmark case of steady-state subsurface fluid flow and transient solute transport along a vertical cross section in an unconfined aquifer. Because of profound geologic heterogeneity, the model must estimate solute ... Читать дальше
Failure of a Multilateral Well
Multilateral wells—those with multiple legs that branch off from a single well—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers must often mechanically stabilize multilateral wells with ... Читать дальше
Discrete Fracture
This example models free flow through a fracture in a block of porous media, where flow in the fracture is much faster than in the matrix block. The Darcy's law physics interface is used to model the flow in the porous block The fracture flow is modeled by adding the Fracture Flow ... Читать дальше
Terzaghi Compaction
Fluids that move through pore spaces in an aquifer or reservoir can shield the porous medium from stress because they bear part of the load from, for instance, overlying rocks, sediments, fluids, and buildings. Withdrawing fluids from the pore space increases the stress the solids bear, ... Читать дальше
Dam Breaking on a Column, Shallow Water Equations
This example uses the Shallow Water equations to model the impact of a water wave on a column. A body of water with a height of 0.3 meters is initially contained behind a gate. At the start of the simulation, the gate is suddenly released and the body of water forms a wave moving toward ... Читать дальше
Aquifer Characterization
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, ... Читать дальше
Tsunami Runup onto a Complex 3D Beach, Monai Valley
This example is an established benchmark case for the shallow water equations that models a 1/400 scaled laboratory experiment of the tsunami runup in Monai Valley in Japan. The experiment was made at the Central Research Institute for Electric Power Industry (CRIEIPI) in Abiko, Japan, ... Читать дальше
Glacier Flow
This example shows how to set up a glacier flow model in principle, containing several important aspects of glacier modeling: The creation of the 2D geometry, the modeling of non-Newtonian flow, and the implementation of basal sliding. In this example, two different glacier types, a cold ... Читать дальше
Phase Change in a Semi-Infinite Soil Column
In this example, a heat-conduction problem with phase change in a porous material is solved, and the results are compared with the analytical solution, also known as the Lunardini solution. This is the first test case from the InterFrost project. https://wiki.lsce.ipsl.fr/interfrost ... Читать дальше
