Following my last thread: /forum/discussion/22323/icem-volume-orientation-probem-mesh-20l-siwek-apparatus#latest

This time, I started the way back by first introducing a perfect O-grid into the sphere which I was able to perfectly section and to associate to the top part of the sphere and to an extruded bounding box at the bottom, which covers the nozzle (see pic).

Up to now, I believe it would be good to try a hybrid HEX-TETRA mesh, but I can't make it work yet. For this, I saw it is necessary to create a floating surface (in my case the cyan surface).

Export .uns for hex mesh as a.unsnExport .uns for tet mesh as b.uns. nOpen a new session. Import both .uns and then use following. nPlease make sure that you have similar sizes on hex and tet side to avoid bad elements. nnRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communityn

DearArrayAfter following your suggestion and looking at the interface between the tetra - hexa meshes, I have some holes in the pyramid elements. Do you know how to get rid of these? nThe Check Mesh option doesn't work so well. These holes introduce bad elements that worsen my overall mesh quality.nHow to make sure the element size between tetra and hexa are ~ similar? Just by eye estimation?nn

There are lot of cell jumps. Please make sure that the mesh is uniform on hex side. Also make sure that same size is applied on tet side. Then only use merge command. nRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communityn
