Using the example there, if we did: ``` amr.refinement_indicators = flame_tracer lo_temp amr.refine.flame_tracer.max_level = 3 amr.refine.flame_tracer.value_greater = 1.e-6 1.e-5 amr.refine.flame_tracer.field_name = Y(H) amr.refine.lo_temp.max_level = 2 amr.refine.lo_temp.value_less = 1000. amr.refine.lo_temp.field_name = temp ``` Then level 0 would be tagged for refinement for Y(H) >= 1.e-6, while level 1 and all higher levels would be tagged for refinement for Y(H) >= 1.e-5. (If a value for every level is not provided, we assume the last value holds for all remaining levels, similar to how we treat quantities like amr.n_error_buf.) ## Additional background This will help for cases where a field varies substantially on the domain and you want to have better control over refinement so that you don't have too many zones. ## Checklist The proposed changes: - [ ] fix a bug or incorrect behavior in AMReX - [x] add new capabilities to AMReX - [ ] changes answers in the test suite to more than roundoff level - [ ] are likely to significantly affect the results of downstream AMReX users - [ ] are described in the proposed changes to the AMReX documentation, if appropriate Src/AmrCore/AMReX_ErrorList.H Src/AmrCore/AMReX_ErrorList.cpp commit 92399587f20875a98655ccbd06a083965cfc9c5c Author: Weiqun Zhang Date: Tue Oct 6 13:30:52 2020 -0700 Hypre with overset (#1439) * Hypre with overset Add overset mask support for hypre. * Keep bottom_verbose restricted to amrex side.

Also adds support for BoomerAMG and Euclid as preconditioners for solvers that can use a preconditioner. - Adds support to parse user options to configure hypre library via AMReX ParmParse interface and input file, using a custom namespace (default is `hypre`) - Adds `MLMG::setHypreOptionsNamespace` that allow applications to customize the namespace for different types of linear solvers (e.g., `mac_proj.hypre.
