help :streamlines bumping head-on into wall -- CFD Online Discussion Forums

November 24, 2003, 13:37	help :streamlines bumping head-on into wall	#1
Subhra Datta Guest Posts: n/a	I am getting some streamlines normal to wall(postprocess :Matlab) and the normal velocity matrix from my Fortran code shows that in those gridpoints adjacent to wall the sense/sign of normal velocity is toward the wall ... I wonder if the remedy is more resolution in grid toward wall or is something seriously wrong with my discretization and boundary conditions (e.g. violation of continuity in those regions).. remedial suggestions will be of gr8 help....
