At that scale, even the smallest problem can cascade into massive waste, affecting a material the nation depends on.

The melting tank itself, they wanted to know what's happening inside of it because you can't, like, see through it, and it's really large.

So they want to know the flow field inside of this large melting tank, and they want to know because they have several points that they can heat up temperature or heat up the tank, and different combinations of these temperatures would have a huge effect on the flow field.

And how the flow field looks like would have a large effect on the final quality of the glass.

Currently, like, what they do is they run a big simulation.

As you can imagine, given how large that melting tank is, the simulation could take weeks or month to run for one set of parameters.

That take too many times, and obviously it costs a lot of money, and it also produce a lot of carbon dioxide.

What once required hundreds of simulations can now happen in seconds.
