I have got a problem in doing meshing in a straight wedge duct which i am using for turbine blade cooling.The mesh I am preferring is Hexa Mesh and o grid around 25 holes.The problem is that when I give premesh command along one side of the edges the mesh gets converge due to which the quality of the mesh is not good also I got too many negative elements this problem become significant as I increase the number of elements.
The region where the problem is concern there are splits which is used to create o-grid. The row where the mesh tends to converge has higher number of elements than the other rows and when i try to change the mesh parameters by giving less elements it automatically takes higher elements by default.What is the possible solution I can get out of this problem?
