I just started using Paraview. I have a dataset with flowfields in .vtu format. I opened them in Paraview and I am facing the following issues:
- Most of my functions including filters, and extractors are greyed out and I am unable to use them.
- I want to extract the Mach Number at selected coordinates but I am only able to extract in terms of Point ID when I open the spreadsheet view.
Kindly help me with this issue as I am very new to the software.
