Some variables not loading in Tecplot

nick.l.thomas · September 20, 2018, 03:56

I am running a transient solution for a vertical axis wind turbine, and when I load the .cgns files in Tecplot there is data missing from some variables. For example, I can create a contour of the x velocity, but when I try to do the same for pressure or y velocity no data loads (the contour is one color). Checking the data set info, the Var status for these missing variables is "not loaded", but loading the variables does not help.

In my .cfx file, under output control > results > output variables list, all the variables I want are listed. Likewise, under output control > export > output variables list, all the variables I want are listed there as well. When running the .res file, I can create contours of all the variables, it's only in Tecplot that the problem exists.

Any ideas what I'm missing here? This is my first attempt at a transient solution so I could be making a pretty basic mistake.

Hello Nick,

If your dataset shows the variables in the Data Set Info dialog, it is likely loaded correctly. I would check in your Data -> Spreadsheet for information about your other variables at each time step. There you can see if any data is located in your files.

If you would like us to take a look at your dataset, you can send it to us at support@tecplot.com. We could get on a call to help talk you through loading your data and getting the relevant Contour plots.

Thanks,
