I’m the beginner of Paraview, so I’m quite sorry for in advance.
My question is I save the data file to ‘csv’ foramt
So, I follow other people’s advice
import CSV file → apply filter(tables to point) → apply filter(Delauay 2D)
so, I would like to see my result with pressure.
However, the problem is when I apply Delaunay 2D I get another strange body parts
so this is what I want
However, if I apply Delaunay 2D filter, I get this result.
Does anyone know how to fix this problem?
I need your help.
Please help me
This is the expected behavior with a concave point cloud.
Thank you fore your reply…
I’m sorry but how do I get exact solution?? I would like to export the figures…
There is no automatic solution, you could manually select the cells you do not want, invert the selection and extract the resulting geometry.
oh…Thank you so much… really helpful to me… . so for spherical model is not good BTW, if I save the data writtn as vtk format, there are no problems such as this problems??
I’m sorry once agian. I need your help… I save my data to VTK file…
and I don’t know what is this… so
So, I use Delaunay 2D once agian…
So, can you tell me how to to select the cells or data from paraview?
and do you know when I import vtk files, why I get this ??
IF I choose ‘point’ I sucessfully see the data… but before selecting point data,
I cannot clearly see my result…
If I do not need to apply delauanay 2D filter, I would like to use another method.
It’s quite complex to eliminate some sells from the paraview
Do you know how to solve this problem?
At first glance, your points data looks like a structured grid points. So instead of the Table To Points filter, the Table To Sturctured Grid filter may be more suitable for you.
Thank you for your reply.
Actually, I followed your opinion and apply Table to structured grid filter…
However, result is same as befreo…
How do to it…?
Would it be possible to share your data?
I can share my data. I attached my grid data.
Please check it.
grid.csv (1.6 MB)
I was able to import the data into ParaView in the following way.
- Add a column of z-coordinates to the csv file and load it into ParaView.
- Next, in the Table To Structured Grid filter, set the settings as shown below and Apply.
Thank you very much. I understand it. I think I made some mistakes.
Then I would like to know, if I save the data to vtk files, I cannot apply filter Table to structred grid… so do you mean, should I have to save the data to csv format in order to solve the problem with delaunay 2D?
This is the fortran code for vtk file format.
As a workaround for the problem of Delaunay 2D, I think it is better to treat the data as Structured Grid Data instead of constructing it from point clouds using Delaunay 2D. So, as a way to handle the data as Structured Grid Data, you can choose to output the data in VTK format or CSV + Table To Structured Grid, whichever is easier to use.
