tdsops_init Function

public function tdsops_init(n_tds, delta, operation, scheme, bc_start, bc_end, stretch, stretch_correct, n_halo, from_to, sym, c_nu, nu0_nu, filter_alpha) result(tdsops)

Constructor function for the tdsops_t class.

'n_tds', 'delta', 'operation', 'scheme', 'bc_start', and 'bc_end' are necessary arguments. The remaining arguments are optional.

'stretch' is for obtaining the correct derivations in a stretched mesh 'stretch_correct' is for correcting the second derivative with the first

'from_to' is necessary for interpolation and staggered derivative, and it can be 'v2p' or 'p2v'. If the specific region the instance is operating is not a boundary region, then 'bc_start' and 'bc_end' are BC_HALO.

'sym' is relevant when the BC is free-slip. If sym is .true. then it means the field we operate on is assumed to be an even function (symmetric, cos type) across the boundary. If it is .false. it means the field is assumed to be an odd function (anti-symmetric, sin type).

'c_nu', 'nu0_nu' are relevant when operation is second order derivative and scheme is compact6-hyperviscous.
