PART 5: Programming in OpenFOAM

[next] [prev] [return to ’solutions’]

  • Simulation involves solving equations
  • Top level OpenFOAM code represents the equations being solved, e.g.

@rU -----+ ~/ •rUU - ~/ •m ~/ U = - ~/ p @t special {t4ht=


    solve
    (
        fvm::ddt(rho, U)
      + fvm::div(phi, U)
      - fvm::laplacian(mu, U)
        ==
      - fvc::grad(p)
    );
