Units in GR Torus

[pcfreak9000]

Hi all.

This is basically my first time using Athena++ and I got quite confused about the units which are used for the in- and outputs. I am using the GR Torus problem generator.

Am I right to assume geometric units G=c=1 for the mass of my central object as well as spacetime coordinates?

In which units do I set the properties of the torus, for example the "rho_max" field? Is this in cgs? Or is this in these ism units as explained in the units and constants wiki? Or, somehow, in geometric units as well?

Thanks for the help! 😄
