Mordicus.Modules.Safran.DataCompressors.IncrementalSnapshotPOD module

Mordicus.Modules.Safran.DataCompressors.IncrementalSnapshotPOD.CompressData(collectionProblemData, solutionName, tolerance, snapshotCorrelationOperator=None, snapshots=None, compressSolutions=False)[source]

Computes a reducedOrderBasis using the SnapshotPOD algorithm, from the snapshots contained in the solutions of name “solutionName” from all problemDatas in collectionProblemData, with tolerance as target accuracy of the data compression

Parameters

  • collectionProblemData (CollectionProblemData) – input collectionProblemData containing the data

  • solutionName (str) – name of the solutions from which snapshots are taken

  • tolerance (float) – target accuracy of the data compression

  • compressSolutions (bool) – decides if solutions may be compressed using the constructed reducedOrderBasis

Returns

of size (numberOfModes, numberOfDOFs)

Return type

np.ndarray
