inciter::Refiner class

static void inciter::Refiner::registerReducers()

Configure Charm++ reduction types.

Since this is a [initnode] routine, the runtime system executes the routine exactly once on every logical node early on in the Charm++ init sequence. Must be static as it is called without an object. See also: Section "Initializations at Program Startup" at in the Charm++ manual http://charm.cs.illinois.edu/manuals/html/charm++/manual.html.

inciter::Refiner::Refiner(const CProxy_Transporter& transporter, const CProxy_Sorter& sorter, const tk::CProxy_MeshWriter& meshwriter, const Scheme& scheme, const tk::RefinerCallback& cbr, const tk::SorterCallback& cbs, const std::vector<std::size_t>& ginpoel, const tk::UnsMesh::CoordMap& coordmap, const std::map<int, std::vector<std::size_t>>& bface, const std::vector<std::size_t>& triinpoel, const std::map<int, std::vector<std::size_t>>& bnode, int nchare) explicit

Constructor.

void inciter::Refiner::dtref(const std::map<int, std::vector<std::size_t>>& bface, const std::map<int, std::vector<std::size_t>>& bnode, const std::vector<std::size_t>& triinpoel)

Start mesh refinement (during time stepping, t>0)

void inciter::Refiner::addBndEdges(CkReductionMsg* msg)

Receive boundary edges from all PEs (including this one)

Receive boundary edges from all refiner chares (including this one)

void inciter::Refiner::refine()

Do a single step of mesh refinemen/derefinementt (only tag edges)

During initial (t<0) mesh refinement, this is a single step in a potentially multiple-entry list of initial adaptive mesh refinement steps. Distribution of the chare-boundary edges must have preceded this step, so that boundary edges (shared by multiple chares) can agree on a refinement that yields a conforming mesh across chare boundaries. During-timestepping (dtref) mesh refinement this is called once, as we only do a single step during time stepping.

void inciter::Refiner::addRefBndEdges(int fromch, const AMR::EdgeData& ed, const std::unordered_set<size_t>& intermediates)

Receive newly added mesh edges and locks on our chare boundary.

Receive edges on our chare boundary from other chares

void inciter::Refiner::correctref()

Correct refinement to arrive at conforming mesh across chare boundaries.

This function is called repeatedly until there is not a a single edge that needs correction for the whole distributed problem to arrive at a conforming mesh across chare boundaries during a mesh refinement step.

void inciter::Refiner::perform()

Perform mesh refinement and decide how to continue.

First the mesh refiner object is called to perform a single step of mesh refinement. Then, if this function is called during a step (potentially multiple levels of) initial AMR, it evaluates whether to do another one. If it is called during time stepping, this concludes the single mesh refinement step and the new mesh is sent to the PDE worker (Discretization).

void inciter::Refiner::sendProxy()

Send Refiner proxy to Discretization objects.

This should be called when bound Discretization chare array elements have already been created.
