Doing so I receive the warning 'Reading file version: 4.2 with older reader version 4.0', suggesting that an outdated vtk version is used to read the file.

But, it looks the filter provides what you are looking for. Based on the documentation of the vktMeshQuality filter (http://www.vtk.org/doc/nightly/html/classvtkMeshQuality.html#details), in addition to the per-cell value in the Quality scalar, there is also a Field Data set that is produced called Mesh Quality. In your case, you are looking for the Mesh Tetrahedron Quality field. The field has 5 components. The first 4 are the ones you are looking for, and they are: > The minimum, average, maximum, and unbiased variance of quality for each type > of cell is stored in the output mesh's FieldData. When you visualize the Mesh Tetrahedron Quality variable, it will default to the Magnitude. If you change it to show component 0 you will get the minimum for each cell, 1 is the average, etc.. The 5th field (component 4) is used internally and doesn't matter.

[Paraview] Glyphs/Streamlines
Hello Community, I am trying to view a vector field (one vector at each vertex stored as 'Point Data') in Paraview 4.2.0 using the 'Glyph' filter. After application of the filter and using the Glyph Type 'Line' I tried to scale these lines (all vectors are unity vectors) in length and diameter, but I haven't found this property and think that this has been possible in older versions. Is this still possible in Paraview 4.2.0? Beside that I was trying to create streamlines from my static vector field. I tried 'Stream Tracer', but that didn't display any result in my case. Can anybody give me a hint on how to start working on that since I have never been doing this, thanks.

Subject: Re: [Paraview] Paraview/Load File and Take Screenshot
You can indeed run a python script from terminal to automate such a
task. Use pvpython or pvbatch executables. Those are simply Python
interpreters with ParaView initialization stub. You can pass in a
script as command line argument and the application will quit once the
script is done.

I have found this link online

which is not very promising, but also hoping that this feature would have
been added since then. I already want to thank you in advance for any help,
merry Xmas!

[Paraview] Tetrahedral Mesh Quality
Hello Community, I need to evaluate the quality of my tetrahedral mesh for simulations in structural mechanics and want to apply the filter 'Mesh Quality' using the 'Scaled Jacobian' metric. Paraview (4.0.1) calculates the values providing me with a range of [0.1,1.0] and the 'Histrogram' looks like a Gauss distribution with a mean around 0.6. I wanted to find out more about how this metric is calculated for tetrahedral elements and looked up the 'Verdict Library Reference Manual', which states the following: acceptable range:[0.500 , 0.707] normal range: [-0.707 , 0.707] full range:[-dbl_max , dbl_max] It also states that the 'Scaled Jacobian' for a unit equilateral tetrahedron, in my humble opinion a perfect tetrahedron, is 1. As far as I understand these ranges the full range provides values if some error/problem occurs, the normal range should be the range of mathematically possible values and the acceptable range is where somebody wants his elements to be in. The 'Scaled Jacobian' of a unit equilateral tetrahedron, however, doesn't fall in the acceptable range or even worse, in the normal range. Do I misunderstand the provided ranges? I also tested a equilateral tetrahedron in Paraview and by hand with the 'Scaled Jacobian' metric and I always obtained 1. Thank you for your help!

[Paraview] Plane visualization
Hello again, sorry, I for to add that I have projected cell data to point data and made a slice within a certain location within the geometry. I want to calculate the mean value of the point data in this slice, is there an already implemented function for that? Thanks!

[Paraview] Plane visualization
Hello, I am searching for an easy way to get rid of the box and the direction vector, but still showing the plane with shading when cutting a geometry in Paraview. Is it also possible to show several planes with the same properties as described above in on image, like I would cut a geometry several times? Thank you!

[Paraview] Statistics/Mesh quality
Hello everyone, I am using Paraview to evaluate mesh quality (scaled Jacobian measurement) and want to know, how many elements have a larger quality measurement than, e.g., 0.8, 0.6, 0.4 and 0.2. Is there an easy way to extract this information? Thank you very much!

[Paraview] Mesh Quality
Dear Madam/Sir, I am a student at Graz University of Technology starting with Paraview 3.10.1 and came up with a question I can not answer myself. I am using the Filter called 'Mesh Quality' with the 'Scaled Jacobian' option for hexahedral elements. I have some elements which have only six different vertices (instead of eight, which leads to a wedge) and the result is a value like 1e+30. I want to analyze this result, because in general the range for a 'Scaled Jacobian' is between -1 and +1. Can you provide me with the equation how this 'Scaled Jacobian' is evaluated in Paraview? If the 'Scaled Jacobian' is evaluated with min(Jk/(norm(e1k)*norm(e2k)*norm(e3k))), where eik are the three edge vectors of vertex k and Jk is the Jacobian at vertex k of a hexahedron (this is evaluated for all 8 vertices and then the minimum is takes), we would get a '0/0' at one vertex of a degenerated hexahedron. I would expect to get an error, but instead I think I get extremely high values. But since the 'Scaled Jacobian' should take the minimum of all values in a hexahedron, I am not sure what is going on there. I have to thank you a thousand times and hope that anyone can help me with my question!
