Mcscf not converged
Did you know?
WebThe MCSCF will use a one-electron approximation to the orbital-orbital Hessian until some degree of convergence is obtained, whereupon it will attempt to use the exact orbital-orbital Hessian which makes the micro iterations more expensive but potentially reduces the total number of macro iterations.

Use $MP2 cutoff=1d-20 $END 3. Use $TRANS cuttrf=1.0d-20 $END 4. Relax acurcy in MCSCF to 1.0d-8 or maybe even to 3.0d-8. acurcy=1d-9 is too tight and often cannot be reached due to finite precision of floating point operations, so no convergence in MCSCF.

The MCSCF Fock matrix is thus Hermitian at this point on the energy surface. This condition has been used as a basis for optimization schemes in earlier developments of the MCSCF methodology. iron marathon
