| Impl (std::shared_ptr< const Context > context) | |
| std::shared_ptr< petsc::DM > | create_dm (unsigned int da_dof, unsigned int stencil_width) const |
Create a DM with the given number of dof (degrees of freedom per grid point) and stencil width. | |
| void | set_ownership_ranges (const std::vector< unsigned int > &procs_x, const std::vector< unsigned int > &procs_y) |
Set processor ownership ranges. Takes care of type conversion (unsigned int -> PetscInt). | |
| void | compute_horizontal_coordinates () |
Compute horizontal spacing parameters dx and dy and grid coordinates using Mx, My, Lx, Ly and periodicity. | |
