Plot
Hi everybody I simulate the rib waveguide with mode analysis and in picture i attack it ,is a 3D plot. I want to convert it to 1D plot in x and y direction.How can i do it?I think it is so easy but i dont know how can i... Read more »

Electric potential and current density analysis
Dear friends, I analyzed a model using Time-dependent solver and for the time: range (0, 0.016,1). The model is consisted of different layers with different conductivity and permittivity and a Terminal with an AC current... Read more »

PDE-interface, implementation of a 'jump' in the dependent variables at a boundary
Dear COMSOL-community, currently I am trying to implement a model (in COMSOL 4.3a) in order to simulate the injection of spin currents from a ferromagnet into a semiconductor via a tunnel barrier. The basic physical... Read more »

Importing real data heat flux boundary condition to COMSOL
Hello all, I'm working on a 2D transient heat transfer project and I can't figure out how to import real data for heat flux vs.time in COMSOL. It only allow me to input a fix value or function, not discrete data points. Any... Read more »

larger ICP model causing problems - singularity error
Hey, I am using your thermal_plasma model as a basis to my model. It is almost the same. The only difference is that in my model the tube is straight (not curved) and longer (0.8 m). These are the dimensions of an ICP system... Read more »
