NLINSOLACCEL

Description	Type	Default
Nonlinear solver iteration acceleration option. Controls nonlinear iteration acceleration, damping, and line search algorithms. There are five options: 0 - No acceleration, damping, or line search controls (OFF). 1 - Damping only. 2 - Line search only. 3 - Acceleration, damping, and line search controls. 4 - Acceleration and damping only (ON). See the NLPARM Bulk Data entry in Section 4, Bulk Data, for additional line search parameters.	0 ≤ Integer ≤ 4 ON/OFF	4
