prepare_input(iodata, nrad, nang, chunk_size, gradient, orbitals, store_atgrids, logger)

Prepare input for denspart with HORTON3 modules.

Parameters:

  • iodata – An instance with IOData containing the necessary data to compute the electron density on the grid.

  • nrad – Number of radial grid points.

  • nang – Number of angular grid points.

  • chunk_size – Number of points on which the density is evaluated in one pass.

  • gradient – When True, also the gradient of the density is computed.

  • orbitals – When True, also the occupied and virtual orbitals are computed.

  • store_atgrids – When True, the atomic grids are also stored.

Returns:

  • grid – A molecular integration grid.

  • data – Qauntities evaluated on the grid, includeing the density.
