Improving Convergence of Transport Equation
 

Hello,

I've included a transport equation running with a convection and source term only, around an aerofoil and wing. Ideally I want this running for inviscid flow under M=0.3-1.0. I'm running this on STAR CCM+ under coupled flow ideal gas models. My transport equation's source term appears to struggle to converge to a solution around the trailing edge due to the curvature and discontinuities that arise, as a result this propagates throughout the domain. What changes could be made in order to alleviate the poor convergence here, would a finer grid or change in discretization help?

Thanks
