[tag] value

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

1 2
3 4

OGS will read the proper 2x2 matrix.

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