What's New

Tecplot Focus 2018 Release 2

Tecplot Focus 2018 R2 is largely focused on our users in the geosciences, but that doesn’t mean there isn’t something for you in this release. Read on to see what’s new. If you don’t see the improvement or bug fix you wanted, let us know what’s missing by contacting us at

For Geoscientists

Sequential – Viridis & cmocean colormaps. Which colormap you use to represent your data makes a difference. Sequential – Viridis is the new default. Also, check out the new cmocean colormaps copyright (c) 2015 Kristen M. Thyng. Get more details on the cmocean colormaps: cmocean on GitHub.

Georeferenced images may now be imported into Tecplot 360. Georeferenced images can provide important context when viewing geographic model results and work with both 3D and 2D plot types. Watch the video: Georeferenced Images in Tecplot 360.

Colormaps (and a new default!)

We’ve added 19 new colormaps to the selection in Tecplot 360, including using Sequential – Viridis by default. Over the past decade, research has revealed many negative aspects of the Rainbow colormap. That same research has suggested better colormaps which are perceptually linear or diverging. This change of default may affect the result of scripts. If you need to switch back to Small Rainbow, you can change the default by adding the following lines (for example) to your tecplot.cfg file:

$!GlobalContour 1 ColorMapName = 'Small Rainbow'
$!GlobalContour 2 ColorMapName = 'Large Rainbow'
$!GlobalContour 3 ColorMapName = 'Diverging – Blue/Red'
$!GlobalContour 4 ColorMapName = 'Small Rainbow'
$!GlobalContour 5 ColorMapName = 'Small Rainbow'
$!GlobalContour 6 ColorMapName = 'Small Rainbow'
$!GlobalContour 7 ColorMapName = 'Small Rainbow'
$!GlobalContour 8 ColorMapName = 'Small Rainbow'

If you have your own custom colormap that you always want available, just drop a *.map file in the new ‘colormaps’ directory in the installation.

Loader Updates

Excel Add-In now includes the filename is Zone Auxiliary Data of each created zone, so you can more easily identify which file the zone originated from.

Multiselect & Context Menus

Tecplot 360 now allows you to group select multiple items, such as text and geometries. We’ve also added brand new context menus for text and geometry objects. Give it a shot by right-clicking when you have a piece of text selected.
