- KrylovSolver.gensubspace(max_dim_q, frequency, check_orthogonality=False, full_file=None)#
Generate a Krylov subspace for model reduction in a harmonic analysis.
This method generates a Krylov subspace used for a model reduction solution in a harmonic analysis. The subspace is built using the assembled matrices and load vector on the
<jobname>.full
file that is located in the current working directory. This FULL file should be built at the specified frequency value.- Parameters:
- max_dim_q
int
Maximum size/dimension of the Krylov subspace.
- frequency
int
Frequency value in Hz to build the Krylov subspace at.
- check_orthogonalitybool,
optional
Whether to check the orthonormal properties of each subspace vector with all other subspace vectors. The result matrix is stored in
KrylovSolver.orthogonality <ansys.mapdl.core.krylov.KrylovSolver.orthogonality
. The default isFalse
.- full_file
str
,optional
Name of the FULL file to read. The default is
<jobname>.full
.
- max_dim_q
- Returns:
AnsMath
Krylov subspace.
