 June 17, 2004, 17:35 mesh #1 zwdi Guest   Posts: n/a Hello, My geometry has a very smal hole with diameter 0.2m. My calculation domain is 500mx200mx100m. I don't want the space around the hole is so densy that make the total mesh size is too huge. How deal with this kind of problem? Does anybody have good ideas to decrease mesh size due to very tiny hole? Thanks a lot. Best regards, Zwdi

 June 18, 2004, 03:54 Re: mesh #2 ap Guest   Posts: n/a I don't know the geometry, but I would think to two possible solutions: - A boundary layer near the hole. . A little volume splitted in the portion where the hole is located. With tetrahedral grids, setting the number of nodes on some edge, it should be possibile to solve your problem. Hi ap

If you have access to fluentusers.com there is documentation there within the online tech section. You will need to registar your name and information to access these areas. Or I cound email the slides for introduction to the size function.

Dear Bob, I will be very glad if I could receive your slides for introduction to the size function by your e-mail. I have no access to fluent user website. My e-mail address is zwdi@yahoo.ca. Dear Ap, I will try to attach the boundary layer around the hole and let you know what will happen next. Thanks again. Best regards, Zwdi
