Hi, Im a studen new with the software, i have watched a few basic tutorials to try to make my project but I´ve faced several problems. I understand that i have to create a geometry 3D model, or in my case import one because i´m using a real model of an aorta, so I import a STL file. This model has no holes for the "tube" so i create them splicing with a cuting plane. Then, due to the complexity of the model, to be able to make the mesh I use the autoskin methods, thus i can make the mesh automatically. Now when i did that a face a problem, when I open the next step, setup, the program shows this ERROR: This appears to be a surface mesh. So i decided to make the model solid in SpaceClaim, but know i face this problem of obsolete mesh and failed mesh. By the way im using Fluent, i saw some works using CFX but CFX in the mesh creation so i changed to Fluent, i guess is okey. What i want to do is just to set the mesh propertly and in the setup place the boundry conditions simply just to make a simulation completly, and then use a full model of subclavias and carotides. 

If you have a step by step tutorial or some tricks or clues for my problem I would apreciate it, I dont know if the problem is in the student version, the stl file. 

Thanks a lot.

Hello Miguel, 

I would suggest using the Fault Tolerant Meshing (FTM) workflow for this. You can import an .stl file directly into Fluent Meshing and use FTM.
