For those interested in connecting structured and unstructured grids, I am currently finishing up work on an addition to Gmsh to interface quad surfaces (even unstructured MIXED quad/tri surfaces!) to unstructured tetrahedral volumes with a single or double layer of pyramids/prisms/tetrahedra. My files should be in a distributable, testable form soon. I am currently debugging, but otherwise it works. I will let Gmsh's creators review it first before delivering it to others.<br>
<br>More to come. <br><br>- Trevor<br>
