Stefan, The idea of identifying each "cell" by a scalar value should work just fine and be scalable.
However, I do not understand what the issue is that the n-th cell's last point is connected to the n+1-th cell's first point. If there is no connection. I honestly do not see anything wrong with the pictures you posted except that in d4.png it looks like the lines of some "cells" are drawn on top of other lines. But that is exactly what I would expect if the cells are adjacent to each other, which I would also expect. The only advice I can think of is to define the scalar values on the triangles (what ParaView calls cells) instead of the points. This will generally be more robust. -Ken -----Original Message----- From: ParaView [mailto:[email protected]] On Behalf Of Stefan Melber Sent: Thursday, September 1, 2016 4:01 AM To: paraview <[email protected]> Subject: [EXTERNAL] [Paraview] Data handling in ParaView Hi, i have (maybe) a simple problem: For the visualization of the so called dual-cells of an unstructured grid i use currently the block-structured vtu-format. The data thereby consists of many complex cells which are itself consists of a number of triangles - see the picture d1 attached. Therefore i have to write out EVERY cell in another vtu-file and group them with am vtm-file together. This way works well with a small number of cells (~1000 - as for the picture) however the aim is to go up to 100e6 cells. Depending on the numbers i got from 1000 cells this process will take ~70 days! The bottleneck is clearly the huge number of files i have to write (and read in ParaView). So are there ideas to have another representation in only one file for such kind of data? I did some experiments writing all cells in one vtk(vtu)-file and give them scalar values depending on the cell number. But then, the n-th cell (its last point) is connected to the n+1 (its first point) and so on. Looks ugly if the n-th cell is not a direct neighbor to the n+1 cell - and that can be the case in my data. And - cutting then the resulting stuff in ParaView i did not get the cutting pictures (like d4) i like to have ...
