[SOLVED] Volumetric Mesh Generation Error

[MA]

I am trying to create a discrete version of a mesh inspired by this example
https://softroboticstoolkit.com/sofa/tutorial/step-1

However, I got this following error, and I dont know how to interpret, I am newbie at meshing

CGAL::Polyhedron_incremental_builder_3<HDS>::
lookup_halfedge(): input error: facet 264 shares a halfedge from vertex 0 to vertex 1 with facet 0.

I dont know what I should do in that case, any hints would be appreciated.

Here I am sharing the steps I did

1- I have created the STL model in blender( this is a single Woven T-yarn of Fabric), as illustrated in the following attachment: https://gofile.io/?c=KKaqnp

2-Later, I have used GMSH to create a volume mesh, I added a physical volume, and 3D mesh and I have also refined the mesh by splitting as shown in the following attachment:

3- For STLIB, is that external plugin, or a plugin to be added in sofa/src/applications/plugins ? I would be grateful for more hints about installation.

Thanks for the help,

Hi @ma1991

What do you call a “discrete version of a mesh”?

@damien-marchaluniv-lille1-fr do you see what could be the problem?

Thanks Hugo, I am referring to the discrete version of volume where I can add constraint to the mesh,

Here is the STL file:
