My application issues the following warning when I attempt to run with FMR.
WARNING[L1,P0] (Carpet): There are not enough time levels for the desired temporal prolongation order in the grid function group "FUNWAVE::MIXING_GROUP". With Carpet::prolongation_order_time=1, you need at least 2 time levels.
I don't sync this group anywhere. Does anyone know why I need two time levels?
Cheers, Steve
