多年来，IFP将CFD应用于理解和开发使用汽油或柴油的内燃机（参见[1]或[2]最近的合作项目示例）。为了充分利用现代并行超标量机（SMP机），IFP最近开发了一种内部求解器[3]，采用新的六维非结构化和并行形式主义设计。图1通过传统直喷式柴油机扇形网格的示例说明了求解器可以处理的新网格设计。现在，自由的适形六面体集可用于离散完整的复杂3D发动机几何形状。为了降低开发成本和时间，选择了OPEN-MP范式进行并行化。这种模式允许我们只处理最消耗CPU时间的例程，并确保工作站和PC上的代码可移植性。
Since years IFP applies CFD for understanding and developing internal combustion engines using gasoline or Diesel fuels (see [1] or [2] for examples of recent partnership works). In order to take full advantages of modern parallel super-scalar machines (SMP machines), IFP has recently developed an in-house solver [3] designed in a new hexaedrical unstructured and parallel formalism. Figure 1 illustrates, through the example of a conventional Direct Injection Diesel sector grid, the new grid design that the solver can handle. Now free sets of conformable hexaedra can be used for discretizing full complex 3D engine geometries. In order to lower the development cost and time, the OPEN-MP paradigm was chosen for parallelization. This paradigm allows us to work only on the most CPU time consuming routines and ensures the code portability on workstations and PCs.
