Notes about the PVTU file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The PVTU file type is primarily associated with 'ParaView' by Kitware, Inc.. ParaView is an application designed with the need to visualize large data sets in mind. ParaView is available as an open-source system. ParaView is a turn-key visualization system built on top of VTK that makes VTK easier to use with a point and click interface.
