#2697: Include BBH+scalar field initial data code from Canuda in ET
Reporter: Cheng-Hsin Cheng Status: new Milestone: Version: Type: enhancement Priority: minor Component:
We propose for inclusion the thorns TwoPunctures_BBHSF and NPScalars_SF from Canuda/Scalar. The codes are hosted in the UIUC branch: [https://bitbucket.org/canuda/scalar/src/Canuda%5C_SF%5C_UIUC/%5D(https://bit...)
TwoPunctures_BBHSF is an initial data solver based on TwoPunctures for a black hole binary plus a cloud of massive scalar field. Namely, it solves the Hamiltonian constraint for the BBH system with back-reaction from a massive scalar field minimally-coupled to GR. Currently, it supports scalar field configurations with vanishing initial momentum and a spherically symmetric or dipolar angular profile, centered at the origin.
NPScalars_SF is an extension of the NPScalars thorn that computes the gravito-electric and gravito-magnetic fields taking into account contributions from the massive scalar field.
