      Both formulations i.e. CSF and CSS, do model the Marangini stress without user defined additional terms. User does not need to specify any additional term. In CSF model, there is explicit calculation for tangential stresses based on surface tension gradient. In CSS model, variable surface treatment is inbuilt.
