Nonlinear Options

These SOLUTION commands are used to define options for nonlinear analyses.

Mapdl.arclen([key, maxarc, minarc])

Activates the arc-length method.

Mapdl.arctrm([lab, val, node, dof])

Controls termination of the solution when the arc-length method is

Specifies buckling analysis options.

Mapdl.cnvtol([lab, value, toler, norm, minref])

Sets convergence values for nonlinear analyses.

Specifies the creep criterion for automatic time stepping.

Mapdl.gst([lab, lab2])

Turns Graphical Solution Tracking (GST) on or off.


Activates a line search to be used with Newton-Raphson.
