Grad

Grad is used to calculate analytic gradients.

General keywords

Nrootgrad

Root number of MCSCF/MRCI for gradient calculation. Default: 1.

maxiter

  • maximum iteration number for solving CPMCHF equation. Default: 500.

mxiter

  • maximum iteration number for update vector in solving CPMCHF equation. Default: 50.

IntCre

  • This keyword can change memory for AOINT saving. maxint=int(maxint*intcre). Default maxint is 268435456.

Ishell

  • This keyword can change memory for AO based DM2. Default is 4 and set shell number is at least one.

CUTCPMC

  • threshold for convergence of CPMCHF equation. Default: 1.d-6.

Printgrad

Controls amount of gradient printing. Default: 0: minimal output.

> 3: print 1-e contributions from S, T, and V.

>99: print all.
