I am learning about 4.0a by trying to get the plasmonic Mie scattering tutorial that worked under 3.5a to run. Note, I realize that a 4.0a version may be released as COMSOL transitions their model database from 3.5a to 4.0a. My efforts now are mostly self-educational.

As could be expected, the old tutorial won't fully import or execute. Orange errors pop up numerous places, making me curious whether variables that previously had to be defined are now reserved or more integrated into the RF module interface. I didn't see a list of intrinsics or reserved names in user help.

In addition, and possibly related, the XML file containing the frequency-dependent (n,k) data for gold doesn't smoothly import. This could be a variable naming problem.

If anyone has any idea how to recreate this model from scratch in 4.0a and can describe step by step using the 3.5a version as comparison, that would be the most helpful.

If there is little or no response, maybe I can post specific questions about some of the errors that I'm receiving while trying to recreate this.

The link to the 3.5a model is here: www.comsol.com/showroom/gallery/3459/
