genericROM.Containers.OperatorCompressionData.OperatorPreCompressionDataThermal module
- class OperatorPreCompressionDataThermal(solutionName, gradPhiAtIntegPoint, phiAtIntegPoint, integrationWeights, listOfTags, integrationWeightsRadiation, phiAtIntegPointRadiationSet)[source]
Bases:
OperatorCompressionDataBaseClass containing an OperatorPreCompressionDataThermal, used in a precomputation of the operator compression step of the POD-ECM method. The implementation uses Lagrange isoparametric finite elements as high-dimension integration model. This structure only depends on the mesh, and is computed once in nongeometrical varitions cases, even when snapshots are updated.
- gradPhiAtIntegPoint

- Type:
list
- phiAtIntegPoint
of size (numberOfIntegrationPoints, numberOfModes), value of the finite element shape functions at the integration points and the integration weights (Lagrange isoparametric finite elements)
- Type:
scipy.sparse.coo_matrix
- integrationWeights
of size (numberOfIntegrationPoints,), vector containing the integration weights associated to the computation of the internal forces vector with the high-fidelity integration scheme
