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.
