[Users] compiling ET on OpenHPC 1.3.5​ and a question

[Hamilton, Maria]

Hello Erik,

Thank you or your prompt reply. Great, I'm glad to learn about the boosted frame, and I'll take a look at it to see if I can use it.  
Sorry for being unclear. I do not need a real GW signal, in fact this will be in my way. 
My intention is to set up a quick experiment to see how the initial junk radiation looks like, and how quickly it leaves the grid. 
Then I want to swap the Cactus provided initial data thorn with one of mine, to see if it makes any difference. 
I'm sure this was done many times before, but not by me. 
I would appreciate if somebody can share with me a parameter file that would work with this version of the Einstein Toolkit. 

thanks,
Maria

Yes, we have an exact solution for a boosted black hole in the
EinsteinExact arrangement. All the solutions there can be put into a
boosted frame. Unfortunately, a boosted black hole will not emit
radiation; it only moves with constant velocity through the domain.

I recommend looking at the tutorial or at the gallery examples from
our home page. There come with some easy to use parameter files to get
started.
