I need some help

I got some files with the suffix VTU by calling the result and I wanted to visualize the result and I didn’t know how to run it. How to find and open the VISIT file in the virtual environment given in the manual.

You need to install visit (VisIt Home) or paraview (https://www.paraview.org/).

Also take a look at a Wolfgang’s lecture 11 and 32: Wolfgang Bangerth's video lectures

Thank you for your guidance!!
