RFCWelements can give invalid results when tracking beams with very large time spread compared to the bunch length.
run_setupdoes not contain any non-numerical parameters of the lattice.
transmute_elementsis used to turn a sextupole into a quadrupole, several problems are seen. Some of the quadrupole parameters are filled with garbage values. When
save_latticeare subsequently used,
elegantcrashes. These problems were reported by V. Sajaev (ANL).
