Who know how to implement AUSMPW+ in 3D curvilinear coordinate .the key is how to define the pressure-weighted function by taking account of transversel direction pressure distribution.in 3d, it should be eight pressure terms? please give me a hand

The calculation of AUSMPW+ in 3d is the simple generalization of the counterpart in 1d if you relace the u in 1d with v.n and adds several metrics. I wonder what the eight pressure terms mean? If you calculate the inviscid flux, you only needs one normal pressure. Meanwhile, if you calculate the viscous flux, you can use central differnece or Gauss theorem.

you can also search Google to find the author of AUSMPW+ and ask him by E-mail. His web site can be easily found.
