amrex::Abort::0::MLMGBndry::setBoxBC: Unknown LinOpBCType !!! SIGABRT

[sachdevakunal]

Hello. I am trying to replicate the "Non-reacting flow past a cylinder" tutorial provided by amrex-combustion under PeleLMeX. I did everything as specified in the tutorial, the only change that i made was turning off the MPI, by doing USE_MPI = FALSE in GNUmakefile.
When I try to run the case by giving the command "./PeleLMeX2d.gnu.ex input.2d-Re500", it gives this error -

Doing initial projection(s)

amrex::Abort::0::MLMGBndry::setBoxBC: Unknown LinOpBCType !!!
SIGABRT
See Backtrace.0 file for details

Can you please tell me where am I going wrong?

Thank you for your time.

It seems that setDomainBC was not called or was called with incorrect BCTypes. Maybe you can ask the question on the PeleLMeX github, and they might have ideas.

Okay. Thanks for your time.

At first, I set the BC of the 2D rectangle as : xlo = Inflow, xhi = Outflow, ylo = Interior/Periodic, yhi = Interior/Periodic, it reported the same error as yours.
So later I set the BC where both ylo & yhi = NoSlipWal, and the error was eliminated.
I'm not sure that is there some connection between the different BC when used in the MLMG class?
