Riadh, I assume updating to non-newtonian viscosity will also be helpful to model oil spill overland (not in waterbodies). For light crude oil, the overland oil flow will behave similar to water, but heavy crude oil will be completely different - mainly laminar flow. Not sure whether I have sufficient knowledge to develop this, but I am more than happy to try it. Can you send me some documentation for me to start? I have a hard copy of the programming guide, do you have any recommendation for the non-newtonian fluid flow? Thanks
