  • A new refinement scheme using the inputs file rather than the Fortran
    tagging namelist has been added. (#1243, #1246) As an example, consider:

    amr.refinement_indicators = dens temp

amr.refine.dens.max_level = 1
amr.refine.dens.value_greater = 2.0
amr.refine.dens.field_name = density

amr.refine.temp.max_level = 2
amr.refine.temp.value_less = 1.0
amr.refine.temp.field_name = Temp

    amr.refinement_indicators is a list of user-defined names for refinement
    schemes. For each defined name, amr.refine. accepts predefined fields
    describing when to tag. In the current implementation, these are max_level
    (maximum level to refine to), start_time (when to start tagging), end_time
    (when to stop tagging), value_greater (value above which we refine),
    value_less (value below which to refine), gradient (absolute value of the
    difference between adjacent cells above which we refine), and field_name
    (name of the string defining the field in the code). If a refinement indicator
    is added, either value_greater, value_less, or gradient must be provided.

  • Automatic problem parameter configuration is now available to every
    problem by placing a _prob_params file in your problem directory.
    Examples can be found in most of the problems in Castro/Exec, and you
    can look at the "Setting Up Your Own Problem" section of the documentation
    for more information. This functionality is optional, however note that
    a file containing a Fortran module named "probdata_module" is now
    automatically generated, so if you have a legacy probdata.F90 file
    containing a module with that name it should be renamed. (#1210)

  • The variable "center" (in the problem namespace) is now part of this
    automatically generated probdata module; at the present time, the only
    valid way to change the problem center to a value other than zero is in
    amrex_probinit(). (#1222)

  • Initialization of these problem parameters is now done automatically for
    you, so a call to probdata_init() is no longer required in amrex_probinit(). (#1226)

  • Problems may now be initialized in C++ instead of Fortran. Instead of implementing
    amrex_probinit() and ca_initdata(), the problem should implement the analogous
    functions initialize_problem() and initialize_problem_state_data(). If you switch to
    the new C++ initialization, be sure to delete your Prob_nd.F90 file. By default both
    implementations do nothing, so you can pick either one but do not pick both. (#1227)

  • The external heat source term routines have been ported to C++
    (#1191). Any problem using an external heat source should look
    convert the code over to C++.

  • The interpolate_nd.F90 file has been moved to Util/interpolate and
    is only compiled into Castro if you set USE_INTERPOLATE=TRUE
