[petsc-users] issues with VecSetValues in petsc 3.19

[Edoardo alinovi]

Sure thing, the solver I am working on is this one:
https://gitlab.com/alie89/flubio-code-fvm.

It is a 3D, collocated, unstructured, finite volume solver for
incompressibility NS. I can run steady, unsteady and I can use SIMPLE, PISO
and Factional step method (both explicit and fully implicit momentum). I
can also solve for turbulence (k-omega, BSL, SST, Spalart-Allmars, LES). I
have also implemented some kind of Immersed boundary (2D/3D) that I need to
resume at some point.

Hot topic of the moment, I am developing a fully coupled pressure based
solver using field-split. What I have now is working ok, I have validated
it on a lot of 2D problems and going on with 3D right now.  If all the
tests are passed, I'll focus on tuning the field splitting which looks to
be a quite interesting topic!

Flubio is a project I have been carrying on since PhD days. The
implementation is 99% on my shoulders, despite the fact I am
collaborating with some people around. I am coding evenings and
weekends/free time, it gives me a lot of satisfaction and also a lot of
insights!
