[Paraview] Saving as csv data

[Moreland, Kenneth]

Teng,

The issue is that your stress field data is associated with the cells and you are writing out the point data in your csv file. Thus, the stress data is not being written. There are two solutions, both with flaws:

Solution 1: When you get the dialog box labeled "Configure Writer (DataSetCSVWriter)" (after you choose a filename), change the option "Field Association" from "Points" to "Cells". If you do this option, you will only get the x, y, and z for the stress (labeled "stress:0", "stress:1", and "stress:2"). You will not get the x, y, z information for the placement of the points.

Solution 2: Before writing out the csv file, run the "Cell Data to Point Data" filter. Then write out the csv file with point data as you have been doing. You will get the x, y, and z for the stress (labeled "stress:0", "stress:1", and "stress:2") and you will also get the positional x, y, and z (labeled "Points:0", "Points:1", and "Points:2"). The problem with this solution is that it will alter the stress data slightly by averaging values of adjacent cells to points.

Also note that neither of these options will automatically write out the magnitude of the stress. To write out the stress magnitude, first run the "Calculator" filter to compute the magnitude of the stress vectors.

Subject: [EXTERNAL] [Paraview] Saving as csv data

Hi all,

I have a question about saving vtk data in a csv file. Please find the following link for the vtk file:

https://drive.google.com/file/d/0B-Dmy2O1v21NbGlfTm9odlZpa2M/view?usp=sharinghttps://drive.google.com/file/d/0B-Dmy2O1v21NbGlfTm9odlZpa2M/view?usp=sharing

I expected to see 7 components in the csv file I saved: x, y, z, stress_x, stress_y, stress_z, stress_magnitude. However, in the csv file I saved, there are only three columns of data. Please find the csv file I saved:

https://drive.google.com/file/d/0B-Dmy2O1v21NeWZnejVqbHEzME0/view?usp=sharinghttps://drive.google.com/file/d/0B-Dmy2O1v21NeWZnejVqbHEzME0/view?usp=sharing

I saved the vtk file by first highlighting the vtk file in the pipeline, and then click save data. Then I used the default settings. Is there anything wrong in my saving process?

Thanks!

Best,
Teng
