Space-Time Transformation of 1D Time-Dependent to a 2D Stationary Simulation Model
Space-Time Transformation of 1D Time-Dependent to a 2D Stationary Simulation Model
Space-Time Finite Element (FEM) Simulation FEATool Multiphysics is a very flexible CAE physics and continuum mechanics simulation toolbox, allowing users to customize, easily define, and solve their own systems of partial differential equations (PDE). In the following it is shown how the custom equation feature can be …
Custom Implementation of an Algebraic Turbulence Model
Custom Implementation of an Algebraic Turbulence Model
Performing accurate simulation of turbulent flows is still a challenging topic today, especially with limited computational resources. Although the Navier-Stokes equations are perfectly valid in the turbulent flow regime, one typically have to resort to some form of turbulence modeling in order to reduce computational …
Physics and FEA Simulations with Parameter Minimization
Physics and FEA Simulations with Parameter Minimization
Featuring an easy to use graphical user interface (GUI), FEATool Multiphysics is also fully compatible with MATLAB functions and its scripting language. As simulation models both can be saved in a binary format and also as m-script language files, FEATool can therefore be used with all built-in MATLAB functionality as …
Inverse Modeling and Parameter Search Using the fzero MATLAB function
Inverse Modeling and Parameter Search Using the fzero MATLAB function
FEATool Multiphysics not only features an easy to use graphical user interface (GUI), but is also fully compatible with the MATLAB scripting language. Models can both be saved in binary format and MATLAB m-script files (every action in the GUI is recorded and has a one to one corresponding FEATool MATLAB function …
Modeling with Non-constant Coefficients in FEATool Multiphysics
Modeling with Non-constant Coefficients in FEATool Multiphysics
FEATool Multiphysics has been designed to be as easy to use as possible, and conveniently features built-in parsing and evaluation of non-constant variables and coefficients. This allows users to quickly and easily enter modeling expressions formulated much as one would write on paper, all without having to develop, …
Periodic Boundary Conditions and the Solver Hook Functionality
Periodic Boundary Conditions and the Solver Hook Functionality
This post describes how to implement finite element FEM models with custom periodic boundary conditions in FEATool. A periodic boundary condition can be defined for opposing boundaries so that their values are linked in some defined way. The typical case for two periodic boundaries is to require them to have identical …
Euler-Bernoulli Beam - FEATool Modeling and Implementation Example
Euler-Bernoulli Beam - FEATool Modeling and Implementation Example
This post will discuss how to implement and model elastic deformations of simple beams with FEATool Multiphysics. Although also available as a pre-defined physics mode and GUI option, beams and truss structures can also be implemented and accurately simulated with slight extension of the available FEM MATLAB functions …
