Re: [Paraview] VTK File Format

[David Lonie]

That's correct -- the cell information specifies the points by index. You
can find more information on the VTK file formats here:

[Paraview] VTK File Format

[Sellmann, Kai Asaad]

Hello everyone!

I have created a vtk File with point coordinates, and cell definitions. As I am 
getting distorted surfaces I was wondering what it could be.

The coordinates are nodal coordinates taken from a FE Model. The elements are 
defined by the IDs of their corresponding nodes.


So it looks kinda like this


...

CELLS 59256 651816
10 21615 1 32020 21623 2 3 4 21625 5 6
10 21623 21615 1 21624 21625 2 5 21627 21626 7
10 8 21623 21612 21615 9 21631 10 11 21625 21621
10 34096 12 34106 1 13 14 34110 15 16 17
10 22735 18 32680 32663 19 20 21 22 23 32682

...


The 10 indicating the number of information "coming up".

So first of all I am little bit confused and would like to know if the cells 
Information is refering to the prior defined Nodes and their IDs?

For example the first line "10 21615 1 32020 21623 2 3 4 21625 5 6" means that 
the first cell consists of the Nodes 21615, 1, 32020, 21623, 2, 3, 4, 21625, 5 
and 6, right? And these nodes are defined like this:


...

POINTS 104667 FLOAT
0 0 0
-0.00133054 -0.0651073 0.00296884
-0.00366651 -0.0661655 0.00448453
-0.00430551 -0.0647424 0.00148457
-0.00664148 -0.0658006 0.00300025
-0.00257653 -0.0641143 0.00448451
-0.0055515 -0.0637484 0.00300024
-0.00147854 -0.0663074 0.00448453
-0.00974145 -0.0646966 0.00299095

...


So the second node (1) of the first element would have the coordinates 
-0.00133054, -0.0651073 and 0.00296884, correct?

If someone has an idea I could send you the .vtk-file


Thnaks,

asaad

Re: [Paraview] Specify render window size

[Mathieu Westphal]

No easy way to do that, but here is a method to be a bit more precise :

1. Create a single view of the size of all views
2. Check the view size in save screenshot window or via python ( eg 999x860)
3. do the computation (999/3  = 333)
4. Set a Tools->"Lock View Size custom" to the correct value (333x860), it
only resize the view, not the view layout
5. Create three view by divising vertically
6. Resize the view layouts manually to align vith the view edge, the
"eye-balling" is much more precise then.

Hope this helps

Regards,


Mathieu Westphal

Re: [Paraview] How to combine multiple domain results into one?

[Mathieu Westphal]

Hello

You can select all your data, then use "Group DataSets" then "Merge Blocks".
