CreateRandomFieldVectors()

int Kratos::PerturbGeometrySubgridUtility::CreateRandomFieldVectors ( )

overridevirtual

Creates Eigenvectors of correlation matrix in a subgrid.

Finds a subgrid (coarser mesh). Generates correlation matrix in subgrid. Decomposes correlation matrix.

Parameters

correlation_matrix	Correlation matrix. Stores correlation value for all nodes in the subgrid.
rPerturbationMatrix	Perturbation matrix. Stores eigenvectors of correlation matrix (column-wise).

Implements Kratos::PerturbGeometryBaseUtility.
