2D shock cappture problem

prapanj

hi friends

i was given a project: capturing shock in a ramp and in front of an aerofoil. I have solved 1D euler equation so far. so i have few doubts.

1. How to device a reflection boundary condition? 2. How to transform the coordinate system.. i mean the geometric coordinates to the mathematical domain.

please drop in a few words and easy methods. from here on i will post my advancement.. I want all your help.

thanking you prapanj
