As has already been discussed on numerous phone and publicly stated at both the RIT and EU ETK 2019 workshops, we would like to include the self-force code in the ET. It will be the first non-Cactus code in the ET. The self-force code is important because it provides a solution for EMRI’s, a class of problems that may be impossible to cover with other methods.
The code is available here: https://bitbucket.org/peterdiener/selfforce-1d/src/master/
The plan is that when the release is made, we will include instructions to checkout and build the self force code on the ET download page, and that the self-force code will have the same tags, e.g. ET_2019_10, as the ET.
