find_all_local_elements Subroutine

public subroutine find_all_local_elements(local_elements, bin_distribution, nbins)

Finds the local virtual elements All elements are mapped at once. Therefore an entry in the resulting array can be used as a lookup index for any of the local element arrays. The distribution itself tells into which array to look.

Arguments

TypeIntentOptionalAttributesName
type(array_i1d_obj), intent(inout), DIMENSION(0:nbins - 1):: local_elements

local virtual elements

integer, intent(in), DIMENSION(:):: bin_distribution

distribution of elements to bins

integer, intent(in) :: nbins

number of bins
