Function documentation

static std::array<std::vector<tk::real>, 3> inciter::centroids(const std::vector<std::size_t>& inpoel, const std::array<std::vector<tk::real>, 3>& coord)
#include <src/Partition/ZoltanGeom.cpp>

Parameters
inpoel in Mesh connectivity with local ids
coord in Node coordinates
Returns Centroids for all cells on this compute node

std::vector<std::size_t> inciter::geomPartMesh(const char* alg, const std::vector<std::string>& zoltan_params, const std::vector<std::size_t>& inpoel, const std::array<std::vector<tk::real>, 3>& coord, int npart)
#include <src/Partition/ZoltanGeom.hpp>

Partition mesh using Zoltan with a geometric partitioner.

Parameters
alg in Partitioning algorithm to use
zoltan_params in Extra parameters pass to zoltan
inpoel in Mesh connectivity with local ids
coord in Node coordinates

Variable documentation

ctr::Config inciter::g_cfg
#include <src/Physics/Zalesak.cpp>

Global-scope data. Initialized by the main chare and distibuted to all PEs by the Charm++ runtime system. Though semantically not const, all these global data should be considered read-only. See also http://charm.cs.illinois.edu/manuals/html/charm++/manual.html. The data below is global-scope because they must be available to all PEs which could be on different machines. Configuration data structure, containing all input data

This object is in global scope, it contains all of user input, and thus it is made available to all PEs for convenience reasons. The runtime system distributes it to all PEs during initialization. Once distributed, the object does not change.

Runge-Kutta coefficients Runge-Kutta coefficients

static const std::array<tk::real, 3> inciter::rkcoef
#include <src/Inciter/LaxCG.cpp>
