If the data file contains more than one item, you must specify which items you want to process.
Items are disabled by selecting 'Not Used', and scalar items are specified as 'Scalar'.
If some of the items constitute a vector field you have to specify which item is the 'Vector X'-component and which is the 'Vector Y'-component. Also, if some of the items constitute a 2. order tensor field, e.g. a stress tensor, you should specify the two normal components 'Tensor XX' and 'Tensor YY' and the shear component 'Tensor XY'.
