Edit: It looks good ( https://github.com/bshambaugh/openfoam-experiments/tree/master/B1_CoarseMesh  ) but there is an error with matching the geometry.

 Maybe I can see what the points are, so that I can change them. Rather than going through the effort to write a parser,

cat points | grep -o "^([0-9].* [0-9].* [0-9].*)"

cat points | grep -o "^([0-9].* [0-9].* [0-9].*)" | sort -rn

Trying the FineMesh and Inlet Mesh together with mergeMeshes, while shrinking before hand, leads to a misaligned mesh. Maybe the mesh merging should be done beforehand, and then the scaling of the meshes should follow.

Okay, I did this and then ran:

transformPoints -scale '(0.00005 0.00001 0.000008571428571428571)'


Now moving to solvers involving pitzDaily, which may or may not be for turbulent flow:

Which one should I chose?? I would like a turbulent flow solver.

I like  this pose from the simplefoam-vs-pisofoam-vs-icofoam thread above: "Hi
icoFoam is transient solver for incompressible, laminar flow of Newtonian fluids.

pimpleFoam is large time-step transient solver for incompressible, flow using the PIMPLE(merged PISO-SIMPLE) algorithm.

pisoFoam is transient solver for incompressible flow.
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.

simpleFoam is steady-state solver for compressible, turbulent flow

Regards

Ata"

Do I want the flow to be compressible or incompressible?
https://www.cfd-online.com/Forums/main/8344-incompressible-compressible-flow.html . I found from this link that the density varies.

Follow Josef Nagy's tutorial, and modify it:

Edit:: For convergence:

Change the Solver
rhoPimpleFoam of compressible fluids for HVAC and similar applications, with optional
mesh motion and mesh topology change
rhoSimpleFoam Steady-state solver for turbulent flow of compressible fluids.
rhoCentralFoam Density-based compressible flow solver based on central-upwind schemes of Kurganov and Tadmor.
