Product Overview

This tutorial teaches you how to implement custom boundary conditions in OpenFOAM using swak4Foam and groovyBC—powerful libraries that let you define boundary behaviors with mathematical expressions instead of coding from scratch. If you’re working on advanced simulations and need flexibility in defining boundary values or gradients, this tutorial provides a practical, step-by-step approach to get you started.

Building on a prior example using codedFixedValue, this tutorial goes further by implementing a wavy boundary motion on a dynamic mesh using expression-based tools. Perfect for CFD users aiming to expand OpenFOAM’s boundary capabilities without diving into C++ programming.
