Postprocessing Surfaces in Fluent

Purpose: This document describes the surface creation methods available in FLUENT. All types of postprocessing surfaces are described, and tips are provided about special features associated with these surfaces.

Introduction

In order to visualize flow features in any 2D or 3D problem, it is necessary to create different types of surfaces at desired locations. Creating these surfaces at a geometry level can be cumbersome; instead they are better handled under postprocessing capabilities.

These surfaces are typically used for:

Displaying the results such as velocity vectors, contours of solution variables, etc.

Generating XY plots

Reporting average values of solution variables, and monitoring them during the simulation

Exporting results to other plotting tools or solvers

Initiating path lines or Injecting particle tracks

A brief summary about commonly used surfaces along with their specific usage is described below:
