Hi Guys,

I need to combine hex and tetrahedral mesh. I have two volumes and they formed in same part. In figure 1 and 2 volumes are shown. As you can see in figures a pipe is connecting with a annular volume. I want to add infilation to pipe. Becouse of hexahedral infilation, highly skewed cells are formed in connection area. You can see the meshes and skewed cells in figure 3,4 and 5. Could you give me an advice about meshing the connection area. By the way i tried the body sizing with sphere of influence to the connection area but it doesnt decrease the skewness.

Best regards.
