Introduction

This tutorial illustrates the setup and solution of a simple 3D problem using the parallel processing capabilities of ANSYS FLUENT. In order to be run in parallel, the mesh must be divided into smaller, evenly sized partitions. Each ANSYS FLUENT process, called a compute node, will solve on a single partition, and information will be passed back and forth across all partition interfaces. The solver of ANSYS FLUENTallows parallel processing on a dedicated parallel machine, or a network of workstations running Windows, UNIX, or Linux.

The tutorial assumes that both ANSYS FLUENT and network communication software have been correctly installed (see the separate installation instructions and related information for details). The case chosen is the mixing elbow problem you solved in Tutorial 1.

This tutorial demonstrates how to do the following:

• Start the parallel version of ANSYS FLUENTusing either Windows or Linux/UNIX.

• Partition a mesh for parallel processing.

• Use a parallel network of workstations.

• Check the performance of the parallel solver.
