5.5.6. SecantNewton Algorithm¶
- algorithm('SecantNewton', iterate='current', increment='current', maxDim=3)
Create a SecantNewton algorithm which uses the two-term update to accelerate the convergence of the ModifiedNewton.
The default “cut-out” values recommended by Crisfield (R1=3.5, R2=0.3) are used.
iterate
(str)Tangent to iterate on,
'current'
,'initial'
,'noTangent'
(optional)increment
(str)Tangent to increment on,
'current'
,'initial'
,'noTangent'
(optional)maxDim
(int)Max number of iterations until the tangent is reformed and the acceleration restarts. (optional)
