Paraview/ParaVis crashes when I use Delanuay 2D filter

Question

I need to make a contour plot in ParaView using the data in a .CSV file (below shows the contents of the CSV file).

1. I opened the .CSV file.
2. I converted the table to points using Apply Filters > Alphabetical > Table to points. It correctly shows the points.

However, when I try to make a surface using Apply Filters > Alphabetical > Delaunay 2D, Paraview crashes without any warning or error message.

I appreciate your help.

Answer 1

I was able to get your data to work by transforming the points by 90 degrees about the x-axis, then applying the Delaunay2D filter. To do so, load the points like you have, apply the Table to Points filter, then apply a Transform filter with the first text box of the "Rotate" setting to 90. Finally, apply the Delaunay2D filter. It should work without crashing.

If you want to get the points back to the original coordinate space, Transform the results of the Delaunay2D filter by -90 degrees about the x-axis.

The likely cause of the crash is that the default setting is to project the points to the XY plane. When you do this with your data, the projected points are colinear, so Delaunay triangulation does not work. I did not bet better results with the Best-Fitting Plane setting.
