5. The underlying idea:
Imagine our world
simulated by a
code… … the man who
wrote the code (the
Architect)…
… and the man who
knew the bugs in
the code (Neo).
12. Every element in the
grid is a
“finite volume”
… and the flow
equations are solved
over the FV
13. The flow equations
Continuity Balance
Momentum Balance
(Navier Stokes)
Heat Transfer
Species Balance
Etc..
14. Each equation is solved
on one cell (FV) in a
sequential manner…
…data obtained on one cell is
used to calculate data on the
next, solving again the same
equations…
…the first cell uses the
BC/IC as initial values
to start with.
15. End result is a grid full of values (v, P, T,
etc.) for each cell
…for your viewing pleasure ;-)
16. How to read what you see
… the idea of flow fields
24. •Create the appropriate domain…
•Create your computational grid…
•Select the right physical models…
•Define your flow materials…
•Prescribe operating conditions…
•Describe boundary conditions…
•Give an initial solution (initialize)…
•Choose solver controls…
•Set monitors and the run!
25. Take a look back…
(Validating your solution)
…is your “matrix” real enough?
26. •Has your solution converged?
•Are your values in the right scale/range?
•Is your y+ in the right range? (later)
•Are your species reacting realistically?
•Does your benchmark problem match with
calculations?
