Hello! I'm trying to calculate the scattering cross section of a gold nanoparticle. However when I change the medium from air to water the simulation can't run... it stops on the first calculation. I change the values of water of the relative permittivity and I added 1.7689 (from n=1.33^2) set the permeability as 1 and keep the rest as comsol default values.... Do you know what is wrong with this?.

Also, I changed the equation of the background electric field by adding the n on the equation: E0exp(-jemw.k01.33x).

Thanks.
