Web12 de jul. de 2024 · A central theme of the OpenFOAM design is that the solver applications, written using the OpenFOAM classes, have a syntax that closely resembles the partial diﬀerential equations being solved. For example the equation is represented by the code solve ( fvm::ddt (rho, U) + fvm::div (phi, U) - fvm::laplacian (mu, U) == - … WebicoFoam solves the incompressible laminar Navier-Stokes equations using the PISO algorithm. The code is inherently transient, requiring an initial condition (such as zero velocity) and boundary conditions. The icoFOAM code can take mesh non-orthogonality into account with successive non-orthogonality iterations.
