nanocomposite meshing

[Austine316]

Hello everyone, I am new here and I hope to get help. I am modeling and simulating my nanocomposite material on a 3-point bending analysis in abaqus. My model is not converging, I believe it is something to do with the meshing. When I run the matrix only, i.e. without the nanotube inside, I get good results which is comparable to my experimental results. However, when i introduce the nanotubes within the matrix, first I get distorted elements when I do the mesh test, and then if I manage to run it, it does not converge. The geometry of my model is 7mm long, 2.5mm width and 0.1mm thick. Nanotube radius is 0.01mm. Please any help will be appreciated.

Um, maybe show a picture of the mesh.
Hopefully you are not trying to mesh an individual nanotube.
