- CompressOperator(collectionProblemData, operatorPreCompressionData, mesh, tolerance, toleranceCompressSnapshotsForRedQuad=0.0)[source]
Operator Compression for the POD and ECM for a thermal problem
- Parameters
collectionProblemData (CollectionProblemData) – definition of the training data in a CollectionProblemData object
mesh (MeshBase) – mesh
tolerance (float) – tolerance for Empirical Cubature Method
- Returns
