For swirler where there is circular vanes I have created Hexa mesh and for rectangular portion of wind tunnel I have created tetra mesh. My fluid flows through the rectangular section into the circular vanes at one crosssection where I have to merge Hexa and Tetra meshes. I am giving the same number of nodes on both the sides. However when number of nodes increases beyond 20 some bad elements get generated in the mesh after merging. For accuracy I have to increase the number of nodes up to 100, which merging is not permitting. Please help.Geometry.jpg Interface after merging.jpg Bad elements in merging.jpg
