kryopt

DynamicOptions.kryopt(maxdim='', restol='', **kwargs)

Specifies solution options for a Krylov method harmonic analysis.

Mechanical APDL Command: KRYOPT

Parameters:

maxdimstr

Maximum dimension of subspace. The default size is automatically determined by the program (ranges around 50).

restolstr

Tolerance used to verify the L-2 norm values of calculated residuals and issue a warning if RESTOL is exceeded throughout the entire frequency range. Default = 0.05.

Notes

This command is used to specify solution options for a harmonic analysis solved with the Krylov method ( Method = KRYLOV on hropt, see also Frequency-Sweep Harmonic Analysis via the Krylov Method

Increasing subspace size ( MAXDIM ) improves solution accuracy with the trade-off of increased computational cost and additional memory requirements.
