    Hi I am very new to Hec-Ras modelling (especially 2D). I tried Hec-Ras 5 Tutor Data “Single 2D Area Internal Dam Structure”. After modelling i found by accident one mesh with negative velocity value in Ras mapper. Please see attachment (print sreen) on link below. What does it mean? Is it error or what? .. thank´s a lot.
