rnrnHi!rnThank you for your reply and these days i have tried a lot of way and finally get it work now.rnFrom the fluid region graph i get, i think the addSlipBoundary function work well now ,but when i run my program as ./Program_name, the command window shows the warning as follow:rnWARNING: Bogus distance at (22,88): 1rnWARNING: Bogus distance at (21,88): 1rnWARNING: Bogus distance at (21,87): 1rnWARNING: Bogus distance at (21,86): 1rnWARNING: Bogus distance at (33,62): 1rnWARNING: Bogus distance at (34,62): 1rnrnrn[BoundaryConditionInstantiator2D] Warning: Could not addSlipBoundary (2, 118), discreteNormal=(0,0,0), set to bounceBackrn[BoundaryConditionInstantiator2D] Warning: Could not addSlipBoundary (2, 0), discreteNormal=(0,0,0), set to bounceBackrn[BoundaryConditionInstantiator2D] Warning: Could not addSlipBoundary (2, 118), discreteNormal=(0,0,0), set to bounceBackrn[BoundaryConditionInstantiator2D] Warning: Could not addSlipBoundary (2, 0), discreteNormal=(0,0,0), set to bounceBackrn[BoundaryConditionInstantiator2D] Warning: Could not addSlipBoundary (2, 118), discreteNormal=(0,0,0), set to bounceBackrn[BoundaryConditionInstantiator2D] Warning: Could not addSlipBoundary (2, 0), discreteNormal=(0,0,0), set to bounceBackrn[BoundaryConditionInstantiator2D] Warning: Could not addSlipBoundary (2, 118), discreteNormal=(0,0,0), set to bounceBackrnrnThese are just a part of the command tips.rnDo you know why?rnrnYour sincerely, Benxi.
