bem_panel_kernel Module

Arguments

Principal-value potential and field of geometry translated by shift, without copying it. The arithmetic is the same as panel_potential_field applied to a geometry whose vertices were translated, evaluated once per vertex distance instead of once per edge end, so the result is bitwise identical. A target on the panel plane falls back to that routine.

Arguments

Principal-value field at target of count translated panels given as component arrays (translated vertex x/y/z per vertex, normal, edge lengths, outward edge normals, area), accumulated into ex, ey, ez divided by k_coulomb as the FMM near field stores it. Entry k carries charge(index(k)); geometry(index(k)) is only read for the on-plane fallback. The SIMD loop performs the operations of panel_potential_field_translated in the same order and the contributions are added in list order, so the sum matches a loop over that routine bit for bit; zero charges are skipped as that loop skips them.

Arguments

Principal-value potential counterpart of panel_field_sum_translated, accumulated into phi divided by k_coulomb.

Arguments

Single-precision counterpart of panel_field_sum_translated. The component tables hold the panels translated by their image shift and relative to the leaf center; target_local is the target in the same frame (double, rounded here) and target the absolute target for the on-plane fallback, which still runs the double-precision kernel on geometry(index(k)) translated by shift1(k), shift2(k) along axes. Eight panels per AVX2 vector; the field error is around 1e-6 relative.

Arguments

Single-precision counterpart of panel_potential_sum_translated; see panel_field_sum_translated_sp.
