Dear COMSOL users,
I am trying to model carbon nanotubes (CNTs) inside an Epoxy and I encountered a few problems, does anyone have a solution?
The model is an Epoxy block with randomly dispersed CNTs inside. These CNTs have a very different resistance than the surrounding Epoxy. With an increasing amount of CNTs the electrical conductance of the block will change. If I model the CNTs as small cylinders or blocks, the meshing seems almost impossible due to the large differences between diameter and length (1:1000). And the mesh of the polymer does not seem to fit.
Therefore I would like to model the CNTs as 2D lines with properties. When I try this with Bezier polygons the electrical conductance solution does not seem to incorporate the geometries inside the Epoxy block. How can I use 2D lines which can be calculated by the AC/DC module?
kind regards,
