Development of advanced manufacturing techniques requires understanding of the underlying manufacturing challenges on a fundamental level.
Solid state batteries are a prime example where we are creating manufacturing techniques as we understand the science.

Honda starting a demo manufacturing line for their solid state battery technology. No details on energy density and overall mass.

The promises of greater range, simplified cooling, durability, safety, simpler manufacturing are worth the investment.

It's extremely important for US automotive to exist and offer options to consumers. New manufacturing processes, materials, technology, design innovation, regulations and capable workforce are critical to success.

Without any of this, a race to the bottom...

So, today the 10 year old got interested in scutoids due to a Vi Hart video, and that led to looking into all sorts of weird shapes, and HOLY SHIT how come nobody told me about trajectoids? www.youtube.com/watch?v=VbuX...

There is certainly value in developing new simulation methods that aren't absolutely accurate. They may be directionally accurate and tell me that a change from the baseline increases or decreases the measured design variables.

This is my current expectation with machine learning and CAE.

Multi-GPU Hybrid computing within #openfoam has been around for a while. In fact, my first big talk at the OFW was speaking about my library coupling within FOAM Extend (github.com/Unofficial-E...) the host-device memory bandwidth bottlenecks at the time were the main reason development slowed.

The OpenFOAM workshop 3 (2008) (OFW3) in Milan (openfoam-extend.sourceforge.net/OpenFOAM_Wor...) was super interesting. The meshing section introduced what would become snappyHexMesh (sourceforge.net/projects/ope...). Almost daily, I use the mesher developed by ENGYS for tough industrial cases
