| module | upf_local_integrals |
| | Local UPF matrix elements from the original radial potential. The Gaussian core electrostatics supplies -Z erf(sqrt(alpha)*r)/r. Its complement is integrated with analytic angles and radial quadrature. Gaussian products, center derivatives and RI integrals share this operator.

| subroutine, public | upf_local_integrals::upf_local_init (pot, alpha, degree, local, eps) |
| | Prepare the short-range local potential outside parallel regions.
|
| subroutine, public | upf_local_integrals::upf_local_matrix (local, la, alpha, lb, beta, rab, rac, v, da, db) |
| | Evaluate primitive three-center local integrals by the Gaussian product theorem.
|
| subroutine, public | upf_local_integrals::upf_local_ri (local, la, zeta, rac, v, dv) |
| | Local potential against a single Cartesian Gaussian for RI.
