Re: [Paraview] Display number of cells over time

[Paraview] problems with vtu format
Hello everybody I've been trying to write down a routine to export the results from my cfd code in paraview format I've been able to work with vtk format but wher I try to write in vtu (xml) format paraview 3.4.0 read the file without giving any errors, the log shows a correct number of cells and points and a listing of all the variables but simply NOTHING appear in the workspace The same behaviour appears both on win and linux machines Can anyone help me guess what's wrong with this file? what should appear is a simple cube made of hexaedrals with different dimensions (as a matter of fact they are clustered near the walls) As it's quite long (almost 1000 points) I won't stick it in this message, I'm trying to zip and attach it; if attachments are not allowed (it's not clear from the ML web page) I've uploaded it on rapidshare (max 10 downloads allowed) http://rs367.rapidshare.com/files/163719862/chan1_180.vtu If not let me just know how to show this file...

Re: [Paraview] : plot
Yes. Look at the first python source example on this wiki page: http://www.paraview.org/Wiki/Here_are_some_more_examples_of_simple_ParaView_3_python_filters. You will have to adapt it to suit your format, changing it to skip over lines starting with %, using white space as a delimiter instead of , and to give each VTK coordinate an Z value of 0.0. cheers, Dave DeMarle 2008/11/14 Samuele Zampini [EMAIL PROTECTED]: Hello, I would like to know if it is possible to plot - with Paraview - such a text file.

Re: [Paraview] scalar to vector filter
I was able to achieve it using the Calculator filter and save my particular expression as a custom filter. This did not unfortunately work for transient data :( Dominik S.

Re: [Paraview] : plot
Samuele, You have to use CVS paraview. This feature is not available in 3.4. With CVS ParaView, you should split the view and create a new XY plot view and then turn on the visibility for this reader in that view.

Re: [Paraview] problems with vtu format
Hey Giovanni, Based on a quick look at the file (with ParaView 3.4, OS X) it seems that all of the point coordinates that make up your cells are located at coordinate (0.1667, 0.0, 0.2281278). So, you can only see anything if you change the representation to Points, where you can see a single point. You can see that the data is in there if you do a Cell Data to Point Data filter and then glyph that with arrows. I'll attach a screenshot.
