Defining / Plotting variables
Posted Oct 1, 2013, 10:05 AM EDT 4 Replies
I've recently started trying to use comsol 4.0a (I'm fairly familiar with 3.5a) and I'm finding it extremely confusing. What I'm trying to do is solve a system with an incident electric field (in a waveguide-like geometry), then use some integrated boundary values of said system to calculate some properties (eg. effective permittivity).
I can do this easily in 3.5a, but in 4.0a the process seems entirely different. In 3.5a I just defined all my variables in the global variables section, solved the system and then went to postprocessing->Global variables plot. I found no such process in 4.0a, I can declare variables, but not plot them and I can't find any way to link my global variables to a data set, infact I can't even see how to solve the system! I realise I'm asking a lot, but after several days of sifting through the COMSOL userguide and COMSOL itself I'm no closer to a solution and my enthusiasm for this (admittedly very powerful) software is beginning to wane. Any help would be much apreciated.
