/IMPL/LBFGS - Parameters of BFGS quasi-Newton Method for Implicit Nonlinear

Description

Change the maximum number of BFGS quasi-Newton method for implicit nonlinear.

Format

/IMPL/LBFGS/L

L

Data

Description

L

Maximum number of BFGS vectors

Comments

1./IMPL/NONLIN/2 should be defined.
2.If L =0 or /IMPL/LBFGS/L is not defined, L = L_A is defined in /IMPL/NONLIN/2.

When this keyword is defined, the new update vectors are accumulated over the old ones by sliding down the set of vectors loosing the oldest ones.
