This millennium will see engineers doing simulation in ways which will inevitably influence how engineering simulation is taught. I expect that teaching innovations will arrive last at M.Sc. and Ph.D. curriculae on high brow Western universities. Simply because the immediate demand for innovation is smallest there.

As discussed here, it is a question of pace. As long as a student is not in danger of making expensive mistakes, there is time to educate so slowly that important insights will mature in the mind of the student.

The introduction of online offerings like SimScale is pure disruption. As stated many places on this website, any person can register with SimScale and perform large-scale number crunching within half an hour. It will of course take longer to create an analysis from scratch. However, SimScale also offers templates which invoke lots of effects and features that a newbie will know nothing about.

100.000+ SimScale users possess an enormous energy and willpower. This will enable them to make big mistakes on rainy days. Not because there is anything wrong with the tools they use. Mistakes will be made due to the imbalance between the power of the tool and the insight of the operator. I feel uncomfortable being alone in my quest for improvement. Therefore, I have asked for help (I know a seasoned teacher when I see one). Until help arrives, you will have to do with me. I will of course answer questions.

As indicated, I will try to present the material in new ways. I will emphasize

  • Conciseness
  • Argumentative self-referencing. If I can support a point through references to previous statements, I will do so.
  • A clear disposition.
  • Many hyperlinks. This will enable the reader to find background information if there is a need for that.
  • Discarding any concept which will not provide immediate insight. Not even this article mentions any Reynolds number.

Of course, all material here is intended to supplement SimScale's own documentation. It also comes without any warranty at all.

Solids

As mentioned here, another idealistic source of information concerning open-source structural analysis software is "feaforall.com".

3D simulation looks like magic - why reduce the dimension count? (October 7, 2017)

Fluids

A different take on viscosity (December 11, 2017, working title: "From scratch to RANS in 1000 words") Btw., I later learnt that I, unknowingly, applied the concept of "Wittgenstein's ladder".
