CFD Gambit Meshing

  1. Jul 17, 2008 #1
    Hi everybody,

    I am Physics graduate now starting a PhD in Bioengineering, and I have been thrown in the deep end to learn Gambit / Fluent for the purposes of blood flow.

    In my undergrad we focused mainly on MathCad and I have no experience of CFD. So I'm really struggling with creating a good mesh.

    I've been at it for a few weeks now and can built geometries successfully and run them in Fluent fine, but when it comes to refining my mesh I'm stuck, they are often poor and I worry about the quality of my results.

    From what I can gather from various sites and links its seems a "stair-step" mesh would probably best suit my problem but I cannot seem to get it to mesh well at all i.e. it constantly creates crude blocky shapes that often don't sit within my volume. One site mentioned using the Edit - Defaults - Mesh section and to change the GOCARTS option. Unfortunately I cannot seem to find GOCARTS option, though it seems that all the other expected options are there.

    Has anyone come across this problem before and perhaps have some advice for me.

    Thanks
