Re: [Paraview] Plain text data with white space delimiters; Use raw array as axis/variables
Thanks, Andy. That works! Now the problem is how I can use the 1d arrays to construct 3d plots. Now I have many 1d arrays: x, y, z, variable1, variable2, ..., etc. Unfortunately, they are AMR data, not regularly indexed, (in fact they are TecPlot ascii data, but ParaView could not read them correctly for some reason, this is another issue, though). I would like to make 3d plots, 2d slice, or at least 1d cuts. I am OK to use Python interface but might need some instruction how to create 3d data from these flattened 1d arrays. I guess there are some tutorials to convert numpy array to vtk arrays, I might start from that. Then I need to convert the row data ParaView GUI reads in to numpy array then to vtk array? I have attached the data if anyone can kindly try it. At least it is a valid TecPlot file which other people tested using TecPlot.

Re: [Paraview] Plain text data with white space delimiters; Use raw array as axis/variables
Hi, ParaView should be able to handle this. Try giving the filename a .csv extension and then add a space for the Field Delimiter Characters options. Optionally, you may also want to enable the Merge Consecutive Delimiters option.

[Paraview] Plain text data with white space delimiters; Use raw array as axis/variables
Hi All, 1) Does the ParaView GUI read a plain text file with white space as delimiters? 2) Can ParaView use a giving 1d array as an axis? My problem: I have a plain text data file, each column is a different variable, and delimiters are white space, e.g., x y z variable1 variable 2 Is there a way to read such a file and use x, y, z as coordinates of the resulting variables? For example, in TecPlot you can read in such a file and set axises to use the x, y, z (or any other named variables). For 1), does ParaView have an extra setting to set common options for plain text data like delimiter, header, skiprow, etc.? For 2), it appears to me that in ParaView all field/cell data is associated with a predefined axis, so it is not that straightforward to use a raw array as axis or as variable, though this is possible in the Python interface. Is this correct.
