Summary0000142: EigenVectors/EigenValues for dimensionedTensorField set wrong dimensions
DescriptionThe functions eigenVectors and eigenValues applied to a dimensionedTensorField return the wrong dimensions

eigenVectors(dimtensorfield f) returns f.dimensions()
eigenValues(dimtensorfield f) returns dimless

It should be the opposite (as correctly implemented in src \ OpenFOAM \ primitives \ Tensor \ tensor \ tensor.C)
eigenVectors(dimtensorfield f) returns dimless
eigenValues(dimtensorfield f) returns f.dimensions()
Additional InformationAs far as I have understood, the error is simple to correct.
In src \OpenFOAM \fields \DimensionedFields \DimensionedTensorField \ DimensionedTensorField.C
