Default How to set initial field for supersonic flows

When I simulate a supersonic inviscid flow arround a airfoil, if I set the inital field according to the free stream, there will be negative pressure at tail edge after some steps. This problem also occurs at the back of a cylind.

Then how to set a good initial field? Or there some other reason?

Thanks
