Was good. Learned Java, which seemes more useful compared to scheme. And this is helpful for a Msc student as with Java, that is a better CV addition than scheme of fluent, which probably no one else uses. I would have liked to have more relevant papers also in place, but those were hard to find. Especially in case of HEEDS

The fact that it has design parameter features, easily integrated, Scripting is easily done compared to Fluent, which for some reason still uses scheme. Also, the post processing is possible in-situ, if I am not wrong.

(Used 2018 version) Design study related things could be included in the regular license. Anyways, each run due to the design parameter usually should add to core usage and hence, be more profitable in my opinion. Also, more scripting tutorial would be helpful.
