Merge VTK files
i'm trying to merge several .vtk files which have the same geomtry but are referred to different timesteps in order to obtain just one file to be processed with Paraview. Anyone knows if exist a filter or a trick to do that?
Thanks in advance
Hi I'm trying to do the same. Did you make any progress?
Greetings to all!
The ".vtk" files are legacy files, which means that they have some limitations on what can be done with them. For example, only 1 time instance can be stored in a single VTK file. You'll have to rely on multiple VTK files, as explained here: http://paraview.org/Wiki/Animating_l...TK_file_series
Although, I did some tests and we still have to rely on several files (using the same criteria explained in the link above) when saving on the more recent VTK format ".vtu".
thanks to the Animating legacy VTK files page I was able to achieve what I wanted to.
My case was split into several sub cases including the time directories. So the vtks were always named starting at ..._1.vtk.
case0280 with vtks case0280_1.vtk, case0280_2.vtk, ... case0280_n.vtk
case0310 with vtks case0310_1.vtk, case0310_2.vtk, ... case0310_n.vtk
So I copied all vtks to a new directory and renamed them (via script) in ascending order and the same suffix:
case_0.vtk ... case_n.vtk
Now everything works fine :-)
A better solution would may be to just link to every *.vtk and have the links named in ascending order. But unfortunately I'm having the data on a FAT formatted HDD which doesn't support symbolic links.
Hi there ,
Could you please tell how did you merge those set of vtk files into one.
I also have set of vtk files like plot01.vtk, plot02.vtk...plot07.vtk. I want to merge those files into one.
If you want to open all of the files in ParaView as a time series, ParaView will shown you a group name "plot..vtk", which you can open directly, without selecting any of the other files; then you can use the play button (the green triangle in the time controls).
The closest to storing all files in a single package will still generate two files. In ParaView, menu "File -> Save Data" and choose the "Xmdf Data file" format, which will create an ".h5" and an ".xmf" file.
