#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\_SF\_UIUC/](https://bitbucket.org/canuda/scalar/src/Canuda_SF_UIUC/)

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.
