DynamicOptions.hropt(method='', value1='', value2='', value3='', value4='', value5='', **kwargs)#

Specifies harmonic analysis options.

Mechanical APDL Command: HROPT

Parameters:
methodstr

Solution method for the harmonic analysis:

  • AUTO - Automatically select the most efficient method (default). Either the full method (FULL) or the frequency-sweep method (VT) is selected, depending on the model. For Method = AUTO, Value1.. Value5 are unused fields.

  • FULL - Full method. For Method = AUTO, Value1.. Value5 are unused fields.

  • MSUP - Mode-superposition method. See HROPT_MSUP.

  • VT - Frequency-sweep (Variational Technology) method (based on the FULL harmonic algorithm). See HROPT_VT_VTPA.

  • VTPA - Frequency-sweep (Variational Technology) perfect absorber method (based on the FULL harmonic algorithm). See HROPT_VT_VTPA.

  • KRYLOV - Frequency-sweep Krylov method. See HROPT_KRYLOV.

    The Krylov approximation can be run using macros as customizable templates as described in. Alternatively, you can perform a Krylov solution without customization as described in Krylov Method Implemented using Mechanical APDL Commands

If the solution method is not specified, the program automatically selects either the Full method or the frequency-sweep method, depending on which method is most efficient for the model. The frequency-sweep method uses the underlying Variational Technology method.

Specifies the method of solution for a harmonic analysis ( antype,HARMIC).

If used in SOLUTION, this command is valid only within the first load step.

This command is also valid in PREP7.

For Method = MSUP:

  • For cyclic symmetry mode-superposition harmonic solutions, MAXMODE and MINMODE are ignored.

  • To include residual vectors in your mode-superposition harmonic analysis, specify resvec,ON.

  • MAXMODE and MINMODE are ignored after a modal restart analysis where remote modal files usage ( moddir ) and residual vector calculation ( resvec,ON) have been activated.
