[vmtk-users] Beginner question

[Vincent Ip <drv...@gm...>]

I am a new beginner in learning how to reconstruct blood vessel from MR angiogram source image for CFD analysis.

I followed the VMTK tutorial step by step to reconstruct the middle cerebral artery and then export it to mesh for FLUENT. But it just doesn't work!

I have a few questions that I don't understand and I really hope someone could show me some guidances (I'm really desperate!!)
- After adding the flow extension, the mesh seems a bit odd and it doesn't look like the one which is depicted as an example on the page of 'generating a mesh'. Is it really necessary to make it or anything I missed to do during the meshing
- And the *.msh file generated (for Fluent) is not readable by Fluent
- I tried the netgen way but I don't know how to use it

I am not sure what did I do wrong but I would appreciate if anyone could advise me on how to generate a proper CFD model from MRA.
Many thanks in advance.
