Mordicus.Core.DataCompressors.SnapshotPOD module¶
- Mordicus.Core.DataCompressors.SnapshotPOD.ComputeReducedOrderBasis(snapshotsIterator, snapshotCorrelationOperator, tolerance)[source]¶
Computes a reducedOrderBasis using the SnapshotPOD algorithm, from the snapshots contained in the iterator snapshotsIterator, which a correlation operator between the snapshots defined by the matrix snapshotCorrelationOperator, with tolerance as target accuracy of the data compression
- Parameters
snapshotsIterator (iterator) – iterator over the snapshots on which we want to compute a reducedOrderBasis
snapshotCorrelationOperator (scipy.sparse.csr) – correlation operator between the snapshots
tolerance (float) – target accuracy of the data compression
- Returns
of size (numberOfModes, numberOfDOFs)
- Return type
np.ndarray
- Mordicus.Core.DataCompressors.SnapshotPOD.ComputeReducedOrderBasisFromCollectionProblemData(collectionProblemData, solutionName, tolerance, snapshotCorrelationOperator=None)[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
snapshotCorrelationOperator (scipy.sparse.csr, optional) – correlation operator between the snapshots
- Returns
of size (numberOfModes, numberOfDOFs)
- Return type
np.ndarray
