Alfred Solving the equations is fast, the slow part is evaluating the solution on the finite differencing grid. If you want to use the same grid multiple times you can checkpoint the initial conditions. If you want to use different grids, then you'll have to repeat the slow part anyway.
There are ways to speed this up by sacrificing accuracy. I don't think this makes sense if you want to obtain accurate waveforms, though. -erik On Wed, Mar 2, 2016 at 9:32 AM, Alfred Castro <[email protected]> wrote: > Hi, > > I am a master student at UIB, and starting to use the Einstein Toolkit > for binary black hole evolutions. > > I am using the TwoPunctures thorn for solving the constraints.
