The numerical value of one of the implemented data types, as given in MaterialPropertyLib::PropertyDataType.

Scalars, vectors (2 or 3 components), symmetric 3D tensors (6 components) and full tensors (4 or 9 components) are supported. Based on the number of components, OGS will deduce the type of the quantity (scalar/vector/tensor, 1D/2D/3D) automatically.

The elements of `<values>`

are in row-major order. I.e., if you write the following into your project file

OGS will read the proper 2x2 matrix.

For the order of symmetric tensor components please refer to the user guide.
