Dear all,

I want to plot data of 3D temperature field (four columns: x y z Temp), and I followed these steps,

> import csv file  
> filter to Table to Points apply  
> set field 0 1 2 to x y z apply  
> filter to Delaunay 3D

but errors out in the third step  
ERROR: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\Filters\General\vtkTableToPolyData.cxx, line 103

Hi,

The following thread may be helpful in solving this.

In Windows 10 you can remove the BOM with _Notepad_

Hi Yoshimi，

Thank you so much and sorry for disturbing you again. For the second step TabletoPoints, it does work well now! However, a new problem occurs. When it comes to the third step Delaunay3D, there may be something wrong with the mesh. The temperature distribution is nearly what I want.

So, how can I fix this, please? Thank you so much.

The **Delaunay3D** filter produces a convex hull. Therefore, it may not be appropriate for non-convex shapes like this one. For this reason, you may need to try another method. For example, since the current shape is a simple shape consisting of two bricks, top and bottom, it may be better to apply the **Point Volumme Interpolator** to each of them.

Below is the State file and the resulting image.

The problem comes from your data source where you have 144 coincident points in the CSV file. If you separate the temperature data for each brick volume into different files the Delaunay3D filter should work; however you then need to combine the output datasets into a single block in Paraview. Someone else can probably answer how difficult/easy that is.
