The kinematic viscosity of the fluid is 0.00047 m^2/s and the density is 850 kg.m^3 (corresponding to some kind of oil). In this example, we consider laminar flow in a pipe (radius 10 mm, length 1000 mm). OpenFOAM with geometry and meshing using other software These steps can be carried out using the singularity container on odyssey. Please familiarize yourself with this model (and the OpenFOAM directory structure) before proceeding further. All steps are carried out in OpenFOAM via command-line interface (CLI). The example of lid-driven cavity flow introduces you to OpenFOAM by taking you through all the steps (geometry creation, meshing, simulation and post-processing) for a simple geometry.

Basics of pre-processing, simulation and post-processing in OpenFOAM In the following sections, we will briefly take you through the modeling steps with a simple example. However, it is more convenient to use a CAD software package for creating more complex geometries and use a separate software for meshing. Simple geometries can be created and meshed within OpenFOAM (see the lid-driven cavity flow example below). These include pre-processing (geometry/part creation and meshing), simulation, and post-processing.

Modeling with OpenFOAM involves multiple steps.
