I have a very good MIKE3 HDFM out put with current speed and current direction with sigma coordinate. I want to find out a 3D flow with current direction of the domain area. In output section of model I just find only current direction of a cross section. But I want to find out current direction with SIGMA level such as vector indication of current direction both surface and bottom as 3 dimensional.  Some please help me to get this.

Thanks to give a time,
