This plots a cross-section through the LaMEM `model`, of the field `field`. If that is a vector or tensor field, specify `dim` to indicate which of the fields you want to see.

This plots a cross-section through a `CartData` dataset `data` of the field `field`, typically read in from a LaMEM simulation.
