Structure for the analysis tuple = (‘Analysis Name’, ‘Value’). 'Analysis Name' defines the reference name for the analysis being specified. The "Value" can either be a JSON String dictionary (see Section JSON String Dictionary) or a single string keyword (see Section Single Value String).
JSON String Dictionary
If "Value" is JSON string dictionary (e.g. "Value" = {"numDesiredEigenvalue": 10, "eigenNormalization": "MASS", "numEstEigenvalue": 1, "extractionMethod": "GIV", "frequencyRange": [0, 10000]}) the following keywords ( = default values) may be used:
-
analysisType = "Modal"
Type of load. Options: "Modal", "Static"
-
analysisLoad = "(no default)"
Single or list of "Load Name"s defined in FEA Load in which to use for the analysis (e.g. "Name1" or ["Name1","Name2",...].
-
analysisConstraint = "(no default)"
Single or list of "Constraint Name"s defined in FEA Constraint in which to use for the analysis (e.g. "Name1" or ["Name1","Name2",...].
-
extractionMethod = "(no default)"
Extraction method for modal analysis.
-
frequencyRange = [0.0, 0.0]
Frequency range of interest for modal analysis.
Note: specifying inf (math.inf or np.inf in Python) results in a blank entry in the input card
-
numDesiredEigenvalue = 0
Number of desired eigenvalues for modal analysis.
A value <= 0 will result in a blank card entry
-
eigenNormalization = "(no default)"
Method of eigenvector renormalization. Options: "DISPLACEMENT", "MASS"
Single Value String
If "Value" is a string, the string value may correspond to an entry in a predefined analysis lookup table. NOT YET IMPLEMENTED!!!!
