nsubst

Mapdl.nsubst(nsbstp='', nsbmx='', nsbmn='', carry='', **kwargs)

Specifies the number of substeps to be taken this load step.

APDL Command: NSUBST

Parameters:

nsbstp

Number of substeps to be used for this load step (i.e., the time step size or frequency increment). If automatic time stepping is used (AUTOTS), NSBSTP defines the size of the first substep.

nsbmx

Maximum number of substeps to be taken (i.e., the minimum time step size) if automatic time stepping is used. The program automatically determines the default based on the physics of the model.

nsbmn

Minimum number of substeps to be taken (i.e., the maximum time step size) if automatic time stepping is used. The program automatically determines the default based on the physics of the model.

carry

Time step carryover key (program-determined default depending on the problem physics):

OFF

Use NSBSTP to define time step at start of each load step.

ON

Use final time step from previous load step as the starting time step (if automatic time stepping is used).

Notes

See DELTIM for an alternative input. It is recommended that all fields of this command be specified for solution efficiency and robustness.

When the arc-length method is active (ARCLEN command), the NSBMX and NSBMN arguments are ignored.

This command is also valid in PREP7.
