The BuckleStep object controls eigenvalue buckling estimation.
The BuckleStep object is derived from the AnalysisStep object.
import step mdb.models[name].steps[name]
This method creates a BuckleStep object.
mdb.models[name].BuckleStep
Required arguments
A String specifying the repository key.
A String specifying the name of the previous step. The new step appears after this step in the list of analysis steps.
An Int specifying the number of eigenvalues to be estimated.
Optional arguments
A String specifying a description of the new step. The default value is an empty string.
A SymbolicConstant specifying the eigensolver. Possible values are SUBSPACE and LANCZOS. The default value is SUBSPACE.
None or a Float specifying the minimum eigenvalue of interest. The default value is None.
None or a Float specifying the maximum eigenvalue of interest. The default value is None.
An Int specifying the number of vectors used in the iteration. The default value is the minimum of (2n, n + 8), where n is the number of eigenvalues requested.
An Int specifying the maximum number of iterations. The default value is 30.
The SymbolicConstant DEFAULT or an Int specifying the size of the Lanczos block steps. The default value is DEFAULT.
The SymbolicConstant DEFAULT or an Int specifying the maximum number of Lanczos block steps within each Lanczos run. The default value is DEFAULT.
Note: minEigen, blockSize, and maxBlocks are ignored unless eigensolver=LANCZOS.
A SymbolicConstant specifying the type of matrix storage. Possible values are SYMMETRIC, UNSYMMETRIC, and SOLVER_DEFAULT. The default value is SOLVER_DEFAULT.
A Boolean specifying whether to retain attributes from an existing step with the same name. The default value is False.
Return value
A BuckleStep object.
Exceptions
RangeError.
This method modifies the BuckleStep object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the BuckleStep method, except for the name, previous, and maintainAttributes arguments.
Return value
Exceptions
RangeError.
