Implicit Residual Smooth of Jameson Scheme -- CFD Online Discussion Forums

November 7, 2010, 09:44	Implicit Residual Smooth of Jameson Scheme	#1
hhuang84 New Member Huang Join Date: Sep 2009 Posts: 11 Rep Power: 16	Hey fellows, I have some problems with implicit residual smooth for vertex based jameson scheme for internal cascade in a C grid. For the Euler solver, whatever the epsilon I chosen, the CFL number fails to increase by a factor of two. it blows up at the wall and the weak cut. Any special treatment is needed for the wall and weak cut? Since for the residual smooth , there is no info about the residual inside of the wall, I picks it to be zero. any hits are appreciated.
