amrex::Vector<amrex::Real> evaluate_source_change(const amrex::MultiFab &source, amrex::Real dt, bool local = false)

Evaluate diagnostics quantities describing the effect of an update on the state. The optional parameter local determines whether we want to do this calculation globally over all processes or locally just on this processor. The latter is useful if you are evaluating the contribution from multiple source changes at once and want to amortize the cost of the parallel reductions. Note that the resultant output is volume-weighted.

Parameters:

• source – MultiFab containing source

• dt – timestep

• local – boolean, do we want to do this calculation globally over all processes or locally just on this processor?

static void print_source_change(const amrex::Vector<amrex::Real> &update)

Print the change due to a given source term update. We assume here that the input array is lined up with the NUM_STATE components of State_Type because we are interested in printing changes to energy, mass, etc.

Parameters:

update – Real Vector of changes

void print_all_source_changes(amrex::Real dt, bool is_new)

For the old-time or new-time sources update, evaluate the change in the state for all source terms, then print the results.

Parameters:

• dt – timestep

• is_new – boolean, do we get the new or old state data?

void evaluate_and_print_source_change(const amrex::MultiFab &source, amrex::Real dt, const std::string &source_name)

Evaluate the change to the state due to sources and then print it.

Parameters:

• source – update to the state

• dt – timestep (will multiply the update)

• source_name – string to associate with this source

static void time_center_source_terms(amrex::MultiFab &S_new, amrex::MultiFab &src_old, amrex::MultiFab &src_new, amrex::Real dt = 1.0)

Center source terms in time, storing in S_new

Parameters:

• S_new – MultiFab to store centered sources in
