Hello Robert,
Is it possible to run computations using the Einstein Toolkit in higher dimensional spaces? Like 1+4.
It is mostly geared towards 1+3. The Carpet driver itself does (or did at one point) support 4 spatial dimensions if one adds:
-DCARPET_DIM=4
to CXXFLAGS in the option list. The respective code is from 2009 so may no longer work as expected.
Other EinsteinToolkit thorns probably will not work though, eg even CartGrid3D will not work and neither will the initial data thorns that expect use coordinates x,y,z.
So you would have to decide what you want to use an most likely (easily) expand them.
Yours, Roland
