Hi all,
It is a second question that might link to a previous one.
My point is that how to convert 2D orphan mesh to 3D solid in Abaqus?
This is short summary regarding my work.
1. I have generated 2D shell mesh by meshlab from point cloud data.
2. I have done mesh repair jobs in Rhino to remove naked and non-manifold edges as well as filling gaps,,,etc. Then export it as .stl file.
3. I have imported this file into Abaqus for stress analysis.
But the mesh is still 2D shell mesh. So, I have to convert 2D to 3D solid before numerical stuff.
4. I have used this order. Mesh ->Edit Mesh-> Convert tri to tet.
Unfortunately, I've met an error. (see the attached first one)
The message says,
"The orphan elements of this mesh do not form a closed shell.
Element edges that are referenced by only one triangular element have been highlighted in red. You must edit the mesh to remove any gaps or overlapping elements before proceeding with this function"
5. Then, go back to PART module for Geometry Edit.
Part-> Tools-> Geometry Edit> Edge -> Stitch (see the attached second one)
But it shows "Part contains no geometry. Add a shell or solid feature first"
Here, I realized that I have to create geometry from orphan mesh.
6. Then, use Part-> Tools-> Geometry Edit> Face -> From element faces to create geometry feature. (see the attached third one)
But it still shows "Mesh to Geometry feature failed"
Now, I don't know how to do.
Anybody any advice?
As far as I know, this does not work in Abaqus. For a 3D part, you need to convert your mesh to IGES ot STEP format.
Alternatively, you can use other programs to mesh the STL directly, like tetgen or gmsh.
You may use Gmsh to make a 3D solid mesh out of STL files !
