Warning 4682

Enrico Silvestri

I've beeing running this file and the system always tells me "WARNING 4682: Coarse triangular mesh of a waveguide port for representing the field distribution of the modes included in the mode expansion"...first of all, what does that mean ? And secondly, what do i need to do to get rid of this warning ? i really just don't understand what's the problem, i fllowed the video tutorial correctly for god's sake

What version of Feko are you using, Enrico? The latest version will automatically have a slightly refined mesh on the waveguide ports compared to the rest of the model. In general, a refined mesh is required on the waveguide ports to represent the model distribution (as modes are launched from that reference surface). If the default refinement is still giving you the warning, add a local mesh on the port faces (for example: use lambda/20 for waveguide ports when using lambda/12 for the rest of the model).
