I don't know why do you want vector graphics for your visualizations. In other words, if you had a new PhD student what would you push them towards for the best quality figures, and what would your workflow look like? Is it possible to do the same with paraview or visit compared to Tecplot? Paraview and visit I haven't used for anything nontrivial, and they seem to have a high barrier to entry.įor me, matplotlib takes a little more learning to get started, but after that you can produce excellent publication quality vector plots in the blink of an eye, far faster and better than in Matlab. It's also very easy to get up and running. Scripting in Tecplot is okay, and reproducing identical figures but with different data is pretty easy by recording macros and editing them. For 2D lineplots I prefer python/matplotlib for pgf graphics with great LaTeX operability, but python lacks flowfield visualization stuff. The vector graphics are okay, but not great, and it's not clear to me how to have the fonts be correctly generated raw by LaTeX. A diverging color map can be very useful in this situation.For those familiar with more of these tools than I am, what are the pros and cons of the various tools available? Right now I exclusively use Tecplot for CFD visualization, but it leaves a lot to be desired. Next, be sure the third frame is selected, and from the Zone Style dialog toggle off all zones but the last one and toggle on the contour.įinally, we can refine the color map to help us better visualize the difference in value. Before clicking Compute, change Zones to Alter to only apply only to the newly created third zone. Now we can now take the difference between the C_p from the change in alpha, open the Specify Equations dialog and using the appropriate syntax to reference the appropriate zones, enter an equation subtracting the coefficient of pressure variable of zone 1 from the same variable of zone 2. Select Data > Create Zone > Duplicate and select the first of the existing zones to create a third zone with the exact same grid. The first step is to create a new placeholder zone to perform the operation without interfering with the existing variable.
We will do the calculations and plot the differences of C_p in this final frame. We will start with a layout showing the Coefficient of Pressure for each data set in a separate frame: The first from our data set with Alpha equal to 0 on the left, and the second with Alpha equal to 11 in the middle.
Note, other input variables such as Mach and Beta remain consistent as well. In this video, we will show how to compare different data sets of similar grids using Tecplot 360.įor this example, we will be looking at the wing surface for two simulations using the same mesh while varying Alpha.
