How to save a volume binary mask to su2 file?

zhang-qiang · December 5, 2022, 09:52

I want to implement a CFD model for a 3D blood vessel. Now, I have the segmentation of the blood vessel, which is a volume binary mask. I wonder how can I obtain the corresponding su2 file using this volume binary mask?

Any suggestion is appreciated~~~

You said previously that you are working in python. I think the best way forward is to write a simple python function to save your data in su2 format, the mesh file is pretty simple:

As you can see, it is basically a collection of points, followed by how the points are connected to form the 3D elements (connectivity information). Is the mesh supposed to consist of 3D hexahedral (cube) elements?
