*SOLUTION TECHNIQUE
Specify alternative solution methods.

This option is used to specify the quasi-Newton method instead of the standard Newton method for solving nonlinear equations or to specify a separated solution scheme for coupled temperature-displacement and coupled thermal-electrical procedures.

Required parameter:

TYPE

Set TYPE=QUASI-NEWTON to specify a quasi-Newton solution method.

Set TYPE=SEPARATED to specify that linearized equations for the individual fields in a fully coupled procedure are to be decoupled and solved separately for each field. This option can be specified only with the *COUPLED THERMAL-ELECTRICAL procedure and the *COUPLED TEMPERATURE-DISPLACEMENT procedure without the ELECTRICAL parameter.

Optional parameter:

REFORM KERNEL

This parameter can be used only with TYPE=QUASI-NEWTON. Set this parameter equal to the number of quasi-Newton iterations allowed before the kernel matrix is reformed. The default is REFORM KERNEL=8.

There are no data lines associated with this option.
