class StructuredMesh : public godzilla::Mesh

Public Functions

StructuredMesh clone() const

Clone this structured mesh object.

Returns:

Clone of this object

void set_stencil_type(DMDAStencilType stype)

Sets the type of the communication stencil.

void set_stencil_width(Int width)

Sets the width of the communication stencil.

void set_sizes(Int M, Int N = 0, Int P = 0)

Sets the number of grid points in the three dimensional directions.

void set_num_procs(Int m, Int n = 0, Int p = 0)

Sets the number of processes in each dimension.

void set_dof(Int n_dofs)

Sets the number of degrees of freedom per vertex.

void set_overlap(Int x, Int y = 0, Int z = 0)

Sets the size of the per-processor overlap.

Parameters:

  • x – Overlap in the x direction

  • y – Overlap in the y direction

  • z – Overlap in the z direction

Public Static Functions

static StructuredMesh create_1d(mpi::Communicator comm, DMBoundaryType bx, Int M, Int dof, Int s)

Creates an object that will manage the communication of one-dimensional regular array data that is distributed across one or more MPI processes.

Parameters:

  • comm – MPI communicator

  • bx – Type of ghost cells at the boundary the array should have, if any. Use DM_BOUNDARY_NONE, DM_BOUNDARY_GHOSTED, or DM_BOUNDARY_PERIODIC.

  • M – Global dimension of the array (that is the number of grid points)

  • dof – Number of degrees of freedom per node

  • s – Stencil width
