Problem with linearized gravity on flat background in spherical coordinates
I am solving the linearized Einstein equations with a flat background in spherical coordinates, i.e $ds^2 = -dt^2 + dr^2 + r^2 d\Omega^2$ and writing $h_{\mu\nu}$ in terms of spherical harmonics. ...

Metric tensor calculation tool? [duplicate]
The Einstein field equations are
$G_{\mu\nu}+\Lambda g_{\mu\nu}=\kappa T_{\mu\nu}$
which would be easy enough to solve if not for all of the nonlinear dependencies on $g$ that the Einstein tensor $G$ ...
