Step-by-Step FieldView Tutorials
The FieldView tutorials walk users step-by-step through FieldView functionality with real-world examples and are included in the FieldView User’s Guide. Each includes read-in of a particular dataset, then demonstrates standard FieldView functionality. Using pictures and specific instructions, users will be guided through reading in and interrogating data and creating meaningful output. Full menus and graphics window representations help keep users on-track through each tutorial. While tutorials are often described by industry, all demonstrate basic capabilities and functionalities of FieldView that can be applied to many types of problems. The datasets for each FieldView Tutorial are available for download below.

Using Feature Detection over an F18, this Fieldview Tutorial includes basics for reading in PLOT3D data and beginning to work with it, exploring data using velocity vectors, pressure profiles, colormaps, and iso-surfaces. The user also learns how to create transparent surfaces and streamlines, and visualize the Mach number. The tutorial’s lessons conclude with displaying the model properties with FieldView functions, 2D plots, and creating complex animation using keyframe animation.
Using an automotive example of in-cylinder flow using a FLUENT-UNS dataset, users will cut away a portion of the surface, visualize vortex formation using velocity vectors and streamlines, seed from a surface and change the way streamlines and vectors are displayed. 2D plots of shear rate and density on a valve are created, scalars are integrated on a surface, and a flipbook animation is created.
Automotive Diesel Combustion
An opposed dual-piston problem is used with KIVA data to demonstrate the creation of a hidden line view of the boundary surface, how to display velocity vectors and fuel concentration over time, amplify the contour range, make two plots of fuel concentration and 3D animations of spray results. The user will finish by displaying the exhaust mass flow rate as a function of crank angle.
In this FieldView tutorial, a catheter is inserted into an artery with a tumor and fluid is injected through a catheter. The user will append, analyze and visualize two datasets. Users will also display shear on the artery wall, unify characteristics between the surfaces, calculate mass flow rate, and visualize stress, concentration, and the flow of medicine.
A three-blade mixer with CFX-4 data is used to examine how to analyze flow in the mixer shafts, examine high/low viscosity regions, automatically add streamline seeds between points, adjust presentation rendering, calculate the impeller flow number, and increase the accuracy of an integration.
Using a combuster, users will create wall boundaries in a PLOT3D file, create filled contours and contours on a scalar surface, visualize the flame envelope, combustion process, and gas temperature, and use streamlines to investigate flow patterns.
FieldView’s feature extraction capabilities are used to examine the flow around and within a water droplet. The user will create and orient the droplet geometry, utilize vortex core and separation/reattachment feature detection tools, show internal flow structures, and create a keyframe animation for all vortex cores.
Free Surface Flow
Using an application from the casting industry, various ways to visualize free surface flow are demonstrated. The user will read and visualize transient FLOW3D data, create IJK surfaces, legends and velocity vectors. This FieldView Tutorial also shows users how to change the colormap settings, display the surface mesh, and clip surfaces using thresholding.
This tutorial focuses on comparing both analytical and visual results directly from 3D data. A heat exchanger dataset is explored. Cartesian data will be converted into cylindrical coordinates, a theta coordinate surface created, and surfaces automatically created from previous datasets. Dataset results are compared, with partial integration used. 2D plots from the surface intersections and keyframe animation from multiple datasets are created.
Using a static mixer simulation, the user will visualize backflow on mixer blades and axial velocities, display shear rates on surfaces, integrate the concentration variance on a surface and display results. Translating surfaces and creating a titled fade-in for a keyframe animation are demonstrated, as is using a FieldView restart file to resume a work session or retrieve accumulated data.
Specific to geometrically periodic data, the dataset is rotated with periodic boundary conditions. Isosurfaces, surface pressure contours, streamlines, and particle paths are used to elucidate flow structures, identify inefficiencies and flow leakage. The tutorial discusses presenting results with annotated images and plots.
This FieldView Tutorial demonstrates the creation and use of streaklines from a transient FieldView Unstructured data file. Streamlines and surface data are managed and animated through transient sweeps and the use of scripts and FieldView data guide are introduced.
Working with FieldView XDB Files
FieldView XDBs are powerful CFD data management tools and the enable high-performance post-processing. The user will learn how to create and import XDB files, use XDBs for dataset sampling, and perform numerical dataset comparisons with sampled data.
This FieldView Tutorial demonstrates how to use FieldView and Octave to perform Proper Orthogonal Decomposition (POD) and FFT on CFD results.
