Sheng is on a distinguished road
I'm a begginer of cfd.
I wrote a program using Jameson's schemes of Euler.But at the second step of Runge-Kutta the density become negtive at the head of airfoil.I think there's something wrong with the boundary condition in my program,because I am not very clear about how to use Riemann conserved quantity.
I want to know how to deal with boundary conditions.
Thank you very much If it's convient for you to sent a program about Jameson's schemes of Euler.Either structed or unstructed ,2D or 3D ,programed by c,c++ or fortran,that's OK.
Thanks for listening.
