<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Samuel,<br>
<br>
ok - interresting idea. I will check out what finally performs better. However - as my tests with the multible block format in vtk (using one binary file for each cell) show, that the handling of more then about 10k files is really a mess. For my final case
i will have around 100M cells - means theoretically 100M files - and this can be a real problem for the filesystem and for paraview ...<br>
<br>
Best regards,<br>
<br>
Stefan<br>

<p><tt>The solution I use for this problem is the PART-construct that is provided by the EnSight gold binary format. My 'PARTS' are defined by material ID's. Each Point datum-item has its own file with all time-steps. Each Cell datum-item has its own file with
all time-steps. I have attached a typical EnSight case-file. (The PART-construct is contained in the individual files.)</tt></p>
<p><tt>ParaView reads this format. EnSight reads this format. If you are interested in pursuing this simulation results format, I can provide the format documentation and an example Fortran95 writer.</tt></p>

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! <br>
<br>
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?
<br>
<br>
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 ...
<br>
<br>
Best regards and hoping for some nice ideas, <br>
<br>
