Re: [Users] Help with GW150914 Black Hole simulation

Hello Enzo, The example parameter file on the website is not set up to produce VTK output, so you will have to manually enable this output to be able to visualize the horizon. You will also have to yourself run the simulation or possible ask the original authors (see the Zenodo entry https://zenod
