modcont

Mapdl.modcont(mlskey='', enforcedkey='', **kwargs)

Specify additional modal analysis options.

APDL Command: MODCONT

Parameters
  • mlskey

    Multiple load step key:

    OFF - Perform the modal analysis (compute the eigenvalues and the load vector) for

    each load step. (default)

    ON - Perform the modal analysis (compute the eigenvalues and the load vector) only

    for the first load step; form the load vector for each subsequent load step (without repeating the eigenvalue calculations) and write all load vectors to the Jobname.MODE file for downstream mode-superposition analyses.

  • enforcedkey

    Enforced motion key:

    OFF - Do not calculate enforced static modes. (default)

    ON - Calculate enforced static modes and write them to the Jobname.MODE file.

Notes

Specifies additional modal analysis (ANTYPE,MODAL) options.

Use the LVSCALE command to apply the desired load in a mode- superposition transient or harmonic analysis.

The maximum number of load vectors that can be used in the downstream mode-superposition transient or harmonic analysis is: 240.

Generation of multiple loads (MLSkey = ON) is supported by the Block Lanczos, PCG Lanczos, Supernode, Subspace, Unsymmetric, and QR damped modal methods.

The enforced motion calculation (EnforcedKey = ON) is supported by the Block Lanczos and Supernode mode extraction methods.
