# 2.4. 2D Lid-driven Cavity Flow
{% hint style="info" %}
This tutorial illustrates the setup and solution of a two-dimensional incompressible laminar flow in a lid-driven cavity. The lid-driven cavity problem \[1] is an important fluid mechanical system serving as a benchmark for testing numerical methods and for studying fundamental aspects of incompressible flows in confined volumes which are driven by the tangential motion of a bounding wall. The lid-driven cavity problem has been used to test the GASFLOW code \[2].
