Copy precomputed Landau quadrature and species data to device-resident Kokkos views for use by LandauKokkosJacobian()

Synopsis

#include "petscdmplex.h"   
PetscErrorCode LandauKokkosStaticDataSet(DM plex, const PetscInt Nq, const PetscInt Nb, const PetscInt batch_sz, const PetscInt num_grids, PetscInt a_numCells[], PetscInt a_species_offset[], PetscInt a_mat_offset[], PetscReal a_nu_alpha[], PetscReal a_nu_beta[], PetscReal a_invMass[], PetscReal a_lambdas[], PetscReal a_invJ[], PetscReal a_x[], PetscReal a_y[], PetscReal a_z[], PetscReal a_w[], LandauStaticData *SData_d)

Collective; No Fortran Support

Input Parameters

• plex - the DMPLEX used to obtain the spatial dimension and discretization tabulation

• Nq - number of quadrature points per element

• Nb - number of basis functions per element

• batch_sz - number of batched vertices

• num_grids - number of grids

• a_numCells - per-grid cell counts (length num_grids)

• a_species_offset - per-grid offset into the flattened species arrays (length num_grids + 1)

• a_mat_offset - per-grid offset into the flattened matrix-block arrays (length num_grids + 1)

• a_nu_alpha - flattened per-species nu alpha collision coefficients

• a_nu_beta - flattened per-species nu beta collision coefficients

• a_invMass - flattened per-species inverse mass

• a_lambdas - flattened grid-pair lambda array of length LANDAU_MAX_GRIDS * LANDAU_MAX_GRIDS

• a_invJ - inverse Jacobians at every quadrature point (length nip * dim * dim)

• a_x - quadrature-point x coordinates (length nip)

• a_y - quadrature-point y coordinates (length nip)

• a_z - quadrature-point z coordinates (length nip, used only when dim == 3)

• a_w - quadrature weights at every quadrature point (length nip)

Output Parameter

• SData_d - the LandauStaticData workspace whose device-resident Kokkos views are allocated and populated

Note

Called by DMPlexLandauCreateVelocitySpace() when the Kokkos backend is selected; not intended for direct user calls.
