Data Types | |
| type | sll_t_sparse_grid_2d |
| Sparse grid object for 2d with interpolation routines. More... | |
Modules | |
| module | sll_m_sparse_grid_2d |
| Implementation of a 2D sparse grid with interpolation routines. | |
Functions/Subroutines | |
| subroutine | interpolate_array_disp_sgfft (interpolator, dim, displacment_in, data_in, data_out) |
| Compute value at displaced grid points using trigonometric interpolation (based on SG FFT) More... | |
| subroutine | initialize_sg2d (interpolator, levels, order, interpolation, interpolation_type, eta_min, eta_max, boundary, modified) |
| Initialize a 2d sparse grid object. More... | |
| subroutine | set_hierarchy_info (interpolator, counter, cdim, lvecin, kvecin, novecin) |
| Helfer function for initialization. Setting all the information needed for node counter of the sparse grid along dimension cdim. More... | |
| subroutine | set_hierarchy_info_boundary (interpolator, counter, cdim, lvecin, kvecin, novecin) |
| Same as set_hierarchy_info but for points on the boundary along dimension cdim. More... | |
| real(kind=f64) function | interpolate_value_sg (interpolator, data, eta) |
| Value at eta interpolated from the hierarchical surplus data using standard sparse grid interpolation. More... | |
| real(kind=f64) function | interpolate_from_hierarchical_surplus (interpolator, data, eta) |
| Implementation of interpolate_value_sg for periodic sparse grid. More... | |
| real(kind=f64) function | interpolate_from_hierarchical_surplus_boundary (interpolator, data, eta) |
| Implementation of interpolate_value_sg for sparse grid with boundary. More... | |
| subroutine | interpolate_const_disp (interpolator, dorder, displacement, data_in, data_out, hiera) |
| Interpolation function for interpolation at (constantly) displaced grid points; displacement only in dimension dim. It is another implementation of the base-class function "interpolate_disp". The advantage is that we can not revisit nodes as we do in the recursive dimension-independently-programmed version. More... | |
| subroutine | interpolate_disp_nconst_in_1d (interpolator, displacement, dorder, data_in, data_out) |
| Functionality: Interpolates the function values for a displacement on in dimension (periodic b.c. i.e. dimension 1 or 2) where the displacement is allowed to be non-constant in one other dimension (Dirichlet b.c. i.e. dimension 3 or 3). More... | |
| subroutine | interpolate_disp_linnconst_in_1d (interpolator, displacement, dorder, data_in, data_out) |
| As interpolate_disp_nconst_in_1d but displacement dependent on displacement*coordinate(dorder(2)) More... | |
| subroutine | fg_to_sg (interpolator, fg_values, sg_values) |
| Set sparse grid values from fg vector. More... | |
| integer(kind=i32) function, dimension(2) | fg_index (interpolator, sg_index) |
| Compute the index of a sparse grid node on level "level" with index "index_on_level" on full grid with of max_level. More... | |
| subroutine | tohierarchical (interpolator, data_in, data_out) |
| Compute Fourier coefficient on sparse grid. More... | |
| subroutine | todehi (interpolator, data_array) |
| subroutine | tohira (interpolator, data_array) |
| subroutine | tonodal (interpolator, data_in, data_out) |
| subroutine | displace (interpolator, dim, displacement, data) |
| Compute the Fourier coefficients of at displaced grid points from Fourier coefficients. More... | |
| subroutine | spfft (interpolator, data_in, data_out) |
| Fourier transform on sparse grid. More... | |

| Inverse Fourier transform. More... | |
| subroutine | filter_highest (interpolator, data) |
| subroutine | filter (interpolator, data) |
| subroutine | linear_filter (interpolator, data, hs, width) |
