Hello,
I rendered 3D aorta model in 3D slicer . I want to load this 3D model in matlab.
Is there any way to load this data?
I want to analyze fluid dynamic simulation study using FEATool extension in matlab.
Thanks for reading.

Volume rendering is a visualization technique. Output of volume rendering is a 2D color image. No data is generated that could be used for FEA. See detailed explanation in this topic:

> Hello, I am a new user on 3D slicer. I was using the display preset feature under volume rendering, and I was wondering if there is a way to save what I was viewing as an .stl or 3D printable file. For example, I was viewing a sample MRI using the CT-cardiac3 preset display. When I tried to save that specific 3D preset displayed sample in a .stl file, the option was unavailable. I was only able to see .vp (volume property), .txt formats. Is there a way to accomplish what I desire in 3D slic…
For FEA, you need volumetric mesh or at least a surface mesh - represented as Model node in Slicer. You can create model from a volume by segment the volume using Segment Editor then export the Segmentation node to Model node.

download cleaver extensions that advertise the capability of generating a volume mesh, but I don’t know whether they are functional and/or maintained.

there is a option for export in matlab

@Michael_Hardisty Could you comment on this? Were you able to use Cleaver extension after all? Have you checked how difficult would it be to upgrade Slicer’s extension to Cleaver2?
