|---|---|
| transporter in | Transporter (host) proxy |
| sorter in | Mesh reordering (sorter) proxy |
| meshwriter in | Mesh writer proxy |
| scheme in | Discretization scheme |
| cbr in | Charm++ callbacks for Refiner |
| cbs in | Charm++ callbacks for Sorter |
| ginpoel in | Mesh connectivity (this chare) using global node IDs |

| triinpoel in | Triangle face connectivity with global IDs |
| bnode in | Node lists of side sets |

void inciter::
Receive shared boundary edges for our mesh chunk.
| Parameters | |
|---|---|
| fromch in | Sender chare ID |
| chares in | Chare ids we share edges with |
void inciter::
Start mesh refinement (during time stepping, t>0)
| Parameters | |
|---|---|
| bface in | Boundary-faces mapped to side set ids |
| bnode in | Boundary-node lists mapped to side set ids |
| triinpoel in | Boundary-face connectivity |
void inciter::
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::
Receive newly added mesh edges and locks on our chare boundary.
| Parameters | |
|---|---|
| fromch in | Chare call coming from |
| ed in | Edges on chare boundary |
| intermediates in | Intermediate nodes |
Receive edges on our chare boundary from other chares
void inciter::
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::
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::
Send Refiner proxy to Discretization objects.
This should be called when bound Discretization chare array elements have already been created.
std::tuple<std::vector<std::string>, std::vector<std::vector<tk::
Get refinement field data in mesh cells.
| Returns | Names and fields of mesh refinement data in mesh cells and nodes |

void inciter::
Pack/Unpack serialize member function.
| Parameters | |
|---|---|
| p in/out | Charm++'s PUP::er serializer object reference |
