OpenFOAM & CFD Simulation Made Easy

CFDTool - Modeling Modes

With the toolbox GUI integrations for OpenFOAM, the complexities of setting up complex and parallel CFD simulations is as much as possible completely automated. The toolboxes automatically meshes, defines and sets up corresponding case files, and solves them, so that users can save time and perform complex CFD simulations without having to think much about it. The GUI can either be used to run full CFD simulations, or as a pre and post-processor for setting up, defining, and postprocessing OpenFOAM simulations, as well as aid to learn OpenFOAM syntax and defining case files.

OpenFOAM CFD Simulation Scripts

Moreover, as each “button click and selection” made in the GUI corresponds to a FEATool Multiphysics function call, also enables directly exporting and running CFD and OpenFOAM simulations as MATLAB scripts. This can be used to easily set up automated parametric simulation runs and parallel studies, and combining simulation models with all available MATLAB scripting functionality and toolboxes.

Furthermore, as every modeling step is recorded the GUI can also be completely automated and played back, which is ideal for producing reproducible step-by-step CFD tutorials, learning, and educational teaching materials.

Multi-CFD Solver Simulation

The unique Multi-Simulation capabilities of FEATool Multiphysics allows one to easily set up and run CFD simulations combined and coupled with completely different physics solvers. This functionality makes it possible to use the most accurate and efficient solvers for different parts of a model, both from the fully integrated GUI and Command Line Interfaces (CLI). One can for example use the CFD solvers OpenFOAM or SU2 for solving for the flow field, and couple it with FEniCS or FEATool for simulation of temperature equations, chemical reactions, and more.

An example of the multi-solver simulation functionality is available as a step-by-step CFD tutorial of modeling cooling via forced convection in a tube and fin heat exchanger. In this multi-simulation model the flow field and fluid dynamics is solved with the OpenFOAM CFD solver, after which the temperature field is solved with the built-in multi-physics solver (using the flow field previously computed with OpenFOAM). Combined with the automatic parallel processing support, the multi-solver simulation functionality saves both computational time and memory, and enables solving more complex and larger scale models not before possible.
