Cool, but someone more educated must enlighten me about "parallel finite element analysis".

Found this: https://www.sciencedirect.com/science/a ... 499090211J

I searched the FrontISTR english manual, and found only one tutorial labeled "Linear static analysis, Parallel". Seems it divides the calculation in to X separate calculations. Which is neat, but does it save computing time on a single computer?

Wow, seams Japanese.

Single computer with multi cores, if you manage well, it should faster than single core.

Yes, of course. But most solvers are using multithreading, I thought "parallel" was a more unique method.
