Web20 de out. de 2016 · I'm currently trying to evaluate the performance of Xeon Phi cards for CFD applications. I was able to compile OpenFOAM (openfoam.org) to be used with a Xeon Phi card. I'm currently able to run a single CFD simulation in parallel (using multiple processes) either on a single card or on multiple cards. For example, I can run … Web4.5.1.1 Solution tolerances. The matrices are sparse, meaning they predominately include coefficients of 0, in segregated, decoupled, finite volume numerics. Consequently, the solvers are generally iterative, i.e. they are based on reducing the equation residual over successive solutions.

"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. " - Openfoam what is phi
