kuse

Mapdl.kuse(key='', **kwargs)

Specifies whether or not to reuse the factorized matrix.

APDL Command: KUSE

Parameters:

key

Reuse key:

• 0 : Program decides whether or not to reuse the previous factorized stiffness matrix.

• 1 : Force the previous factorized stiffness matrix to be reused. Used mainly in a restart. Forcing reuse of the matrix is a nonstandard use of the program, and should be done with caution. For instance, using this option and changing the number of elements, or the number or type of degrees of freedom, may cause an abort.

• -1 : All element matrices are reformed and are used to reform a new factorized stiffness matrix.

Notes

Overrides the program logic to determine whether or not to reuse the previous factorized stiffness matrix for each substep of this load step. Applies only to static or full transient analyses and to full harmonic analyses if the frequency is not changed for continuing loadsteps. For full harmonic analyses, only KEY = 1 or KEY = 0 is valid.

This command is also valid in PREP7.
