Accurate Computational Fluid Dynamics CFD Simulations
In computational fluid dynamics (CFD) simulations accuracy is often very important, especially for drag and lift values. References [1-2] describe a CFD benchmark problem for time-dependent flow around a cylinder where the Reynolds number varies between 0<=Re<=100. The references contain very accuratly …
Modeling with Custom Equations in the FEATool GUI
FEATool Multiphysics features an equation parser which allows users to very easily implement and simulate custom systems of equations. The goal as always with FEATool is to make it as easy as possible, the parser can therefore interpret equations written almost as one would on paper. For example a two dimensional …
Adding Multiphysics Equations and Using Complex Expressions
The FEATool GUI makes it easy to add and coupled multiphysics equations and complex expressions to your models. This post illustrates how to do this. After starting to work with a physics mode it is easy to add one or more other modes by going to the + tab in the Equation Settings dialog box. There you can simply …
