Modelling small fibres
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...

Dear Rutger, I see your point. In your model, only the domain condition (current conservation) is used. The tubes (the edges) will need an additional condition. In principle, this would go as follows:...

If the conductivity of your fibres is orders of magnitude larger than the conductivity of the epoxy you can assume constant potential throughout every single fibre. Or it would be more correct to say...

Indeed, we've tried that as well. If I'm not mistaken, that implementation too resulted in singular behaviour. So when you follow the equipotential implementation, please check for mesh convergence! By...

Hi Durk, I am distributing CNT's inside a polymer, I solved the problems for meshing but i want to know "how to input tunneling properties between CNT's and tunneling between CNT's and my terminals". I...

Dear Laveen, Please take into consideration the electric currents interface solves an ordinary diffusion equation (Poisson's equation or "heat" equation), for current conservation. It treats the medium...

Thanks Durk. I will check with moving mesh and also check with the example.. Thanks for your valauble suggestion. Regards, Laveen Dear Laveen, Please take into consideration the electric currents...
