◆ N_local_points

unsigned oomph::Locate_zeta_helpers::N_local_points = 5

Number of points along one dimension of each element used to create coordinates within the element in order to see which has the smallest initial residual (and is therefore used as the initial guess in the Newton method when locating coordinate)
