Plot over line question
2 Attachment(s)
Hi all,
I really don't know how to explain this: Is there any way to get a "plot over line" plot, where only the cell center values of a cell are shown? I want to see the numerical (spatial) resolution of my grid in the plot, to see if all calculated curves are sampled sufficiently. Basically, I want exactly what I get when I do an x-y-plot in Ansys Fluent. In the surface plot you can see the cell size / spatial resolution: Attachment 28802 The plot over line is always equally sampled: Attachment 28803 Thanks for any help! Philipp. |
Greetings Philipp,
Took me a while to think about this, but I believe I know what you're looking for. The steps should be as follows:

Hi,
Maybe you are looking for 'Point Data To Cell Data' filter? I've attached comparison of the Plot Over Line with and without applying the filter. Steps in the plot over line after point data to cell data correspond to the cells of the mesh. |

Thank you so much for your help. I have tried this, but would really like to plot the cell data vs the y-coordinates ( Points (1) ). Do you know of a way? Thanks, Carla |

Thank you for your advice in this post, is really helping me to understand how Paraview works :) I still have a doubt that I hope you can solve: Basically I would like to retrieve Boundary Layer data using Paraview, and obviously 'Plot Over Line' is not the correct choice. The thing is that if I use the 'Slice' filter over a normal line from the surface, the conflict could appear if the 'slicing line' does not follow a perfect normal direction from the surface. Retrieving cell data in that way can imply the appearance of noise, can't it? Thank you in advance. Alex |

Sorry, but only today did I finally manage to look into your question. Essentially the solution is that you should:

Hi Bruno and others;
I am trying to analyze flow in a channel and I am looking at the velocity field at various locations in the channel domain. I see some bumps along my plot over line and guess it is only because of the interpolation of the cell data's along the line. I have tried several combinations of Bruno's 5 step advice but was unsuccessful. I guess I am doing something wrong straight away. 1. I initially upload my .VTK file 2. Now, I can slice a section, -> How can you apply another slice over this? I tried and it shows nothing which isnt surprising for me. What have I understood wrong here? Thanks; Saideep |
