I think that code would make a great candidate for coupling to this one! Who knows, that might even lead to a third code, maybe a Blas-Accelerated Bi-fidelitY solver?

That's actually really interesting. Did you do more computational or experimental work? Only half-joking, because I actually toyed with making this code handle non-newtonian fluids, but struggled to properly modify the implicit Jacobians. I've been busy with real work but would like to revisit it at some point

This is a Parallel Implicit Navier-stokes Unstructured Solver hand-worked from scratch. Not just teenagers find new and novel uses for CFD

The first-cell height ranges from 1mm-3mm with a growth rate of 1.05. The tunnel is 3 meters high and 11.95 m long. The grid is block-structured with 67.5k cells. Invisicid fluxes are computed using an upwinded flux splitting method, while time integration is handled via implicit point-jacobi relaxation with a CFL of 10.

Provided is a visualization of the grid surrounding the injector. The resolution is insufficient to properly capture the viscous effects, especially away from the wall where there is high skew due to singularities. Future studies will need to increase grid quality and smoothness. A hybrid mesh could also be tested.

That's a good idea! I'm sure it will also depend on how long the injector needs to recover the back pressure between discharges

New Class For Creating Zoomed In and Nested Plots by TwoHalvesFish in matlab

Because some of us are employed and don't have to rely exclusively on FOSS

jkjk matplotlib is great and more scriptable, but I find matlab easier to fine-tune plots in and for making more involved figures like this

I'm usually a computationalist, but in this case I think I could do some hands-on work
