// superclass destructor from KSPACE/pair_lj_charmmfsw_coul_long.cpp:81
  // resets force->qqr2e = force->qqr2e_lammps_real at end of timestep 0
  // causing ~E-6 errors for steps 1,2,... everywhere in this class when
  // running kokkos with openmp (and probably with GPUs also).
  //
  // WORKAROUND: for now until guidance from lammps devs is to
  // reset it back force->qqr2e = force->qqr2e_charmm_real here.
