Hello
I am a master's student working on general relativity and in my project we have gotten to a point where we need to solve the Einstein equations. We are not numerical relativity experts but we have started getting familiarized with the Einstein Toolkit.
After playing with it for a while I have realized that I can’t even run a very simple example where I get the TOV equilibrium parameter file from the par folder of the ET installation and modify it to take it a little bit out of equilibrium and see it numerically evolve back to a new equilibrium situation (say for example changing the density profile). I have tried modifying rho_central in the file tov_star.par however it seems that after that modification the system does not evolve to a new equilibrium. I was wondering if somebody here can point me in the right direction. Thank you so much in advance.
