August 4, 2014, 10:09	Residual Jacobian Matrix For Viscous Nodes	#1
Ashkaari New Member Ashkaari Join Date: May 2014 Posts: 5 Rep Power: 11	Hello! I'm working on a flow solver for NS equations. The LU-SGS method is used. And I am not sure about how to deal with the residual jacobian for wall nodes. Because of no-slip and isothermal wall conditions, residual of velocity is 0. So is it suitable to simply set entries of second and third row of jacobian all 0?
