How to Use the Well Feature in Subsurface Flow Models

Nancy Bannach August 21, 2017

As of version 5.3 of the COMSOL Multiphysics® software, the Subsurface Flow Module includes useful new features that enable you to set up complex modeling tasks more efficiently. For example, when modeling wells, meshing is significantly easier and is more intuitive to set up with the Well feature. In this blog post, we look at the Well feature, discussing how to use it and ways it enhances the modeling process.

Thermoelectric coolers come in various types and sizes, including single-stage and multistage devices. Their application area is large, as they are used in both consumer products like cooling boxes and as temperature controllers in satellites. If you are looking to analyze the design of a thermoelectric cooler and optimize it for a specific application area, a simulation app is an efficient way to accomplish your goals. We discuss how to use the Thermoelectric Cooler demo app in this blog post.

Modeling complex geometries with thin structures can be very costly in terms of computational effort, particularly as such structures require quite a lot of mesh elements in order to resolve them. COMSOL Multiphysics provides dedicated features for modeling thin structures so that such models can be solved efficiently while maintaining accuracy. To set up and postprocess thin structures, COMSOL Multiphysics also provides specialized operators to help you consider all the relevant parameters required for accurate results.

Fluid flow is involved in many engineering applications. In addition to typical CFD simulations, which replace experiments in wind tunnels, flow must also be considered in the cooling of electronic devices or in the chemical industry, where reacting species are transported by a fluid. COMSOL Multiphysics offers dedicated interfaces for various flow types. When should we use the Laminar Flow or Turbulent Flow interface?
