Hi, 

I am a new user of Einstein Toolkit, using the latest version (ET_2022_11). I have recently encountered issues with the Lean thorn that lead to warnings concerning the registered boundary conditions. I filed a bug report here. And possibly related to issue #2651. 

To reproduce the issue, just add the line Cactus::presync_mode = "mixed-warn" to the Lean_inspiral_d06_mres.par file in repos/lean_public/par/.

The warnings I get look like: -> No boundary conditions registered for variables in group LEANBSSNMOL::GAMMAT. The unregistered variable(s) is(are) LEANBSSNMOL::gammatx, LEANBSSNMOL::gammaty, LEANBSSNMOL::gammatz.

I am happy to produce any extra information needed. Thanks!
