Calculation of electrostatic potential of Electrostatic Trap using the Poisson–Boltzmann equation

Please login with a confirmed email address before reporting spam


I am trying to redo the simulation of an electrostatic trap mentioned in the below paper: Geometry-induced electrostatic trapping of nanometric objects in a fluid. Madhavi Krishnan

But I cannot get the simualtion results such as given in figure 3 of the paper. I have attached the model file below, can someone please check and see what is the issue with my model. If you go to the paper the detail of the comsol simualtion is in the mothod summary which is at the end of this paper.

Thank you.
