Just so we don't have a misunderstanding: I put "the fastest" in quotation marks not because I doubt the claim. The code is...

Using lower precision to get a smaller memory footprint and higher performance is perfectly reasonable IMHO, and not some hack hack to cheat your way to the...

The F1 racecar in the youtube video is rather a best-case scenario, since the computational domain is a rectangular box after all. But even here you see the limitation of this...

That's probably a fair analogy for this project, and why it claims to be "the fastest". But let's not get carried away here. This seems to be a fairly small project. If it was really done entirely...

There are lots of simulation types with real-world relevance that would not benefit from FP64 at all. And you can certainly use some...

I'm talking about the ability to represent different parts of the computational domain with different cell sizes. I'll keep using the term cell size when referring to the minimum distance between two...

Powerflow doesn't necessarily need to be the fastest in order to compete with that. They have grid refinements. Which -depending on the case- can reduce computational effort by orders of magnitude....
