Thank you Zach for your reply, that clears it up. I have one more question then. Since I was not able to run the code in my laptop, I tried downloading the datafiles from the following site.
https://zenodo.org/record/155394 I run into the following problem. When following the tutorial example in ' https://docs.einsteintoolkit.org/et-docs/GW150914_VisIt_Tutorial ' on the section "A visualization example", it shows a long folder of surface01_00xxxxx.vtk datafiles, all of which are different time steps for the black hole horizons. But when looking at the downloaded file, I cannot seem to find all these .vtk files. Instead I only find one .vtk file, and therefore am unable to run the complete simulation. Does anyone understand what's going on? Thank you so much for your help.
