FieldView is a powerful commercial post-processing suite available from Intelligent Light.   FieldView allows the engineer to easily identify important flow features and characteristics of flow simulations. FieldView supports both structured and unstructured CFD visualization. One of FieldViews strengths is the ability to handle very large datasets and create complex animations. FieldView allows the engineer to easily probe the data set in regions of interest and extract data from intersection of surfaces or along lines.

TecPlot 360 is the newest visualization package available from Tecplot Inc. TecPlot 360 combines engineering plotting (xy plotting) with advanced data visualization into one package.   TecPlot 360 allows the user to quickly plot and animate all of the CFD data as well as analyze complex data and create professional images. TecPlot 360 supports both structured and unstructured CFD visualization. TecPlot 360 is the primary visualization package supported by the Cart3D software.

Paraview is an open-source visualization package based on the open-source VTK libraries and Qt. Paraview supports both interactive and batch visualization processing. Paraview was developed with large datasets in mind and supports the ability to visualize datasets utilizing distributed memory computing resources. Paraview supports both structured and unstructured CFD visualization. Paraview is free to users but subject to the licensing restrictions found at their website.

Visit is a free, open-source, distributed parallel visualization tool kit available from Lawerence Livermore.   Similar to Paraview, Visit is based on the open-source VTK libraries and was developed for visualization of terabyte datasets. Visit supports a large array of input file formats available as plug-ins. This includes plug-ins for the mainstream files types including CGNS, EnSight, Plot3D, TecPlot, and VTK. Visit supports both structured and unstructured CFD visualization.
