time step continuity errors:时间步的迭代差 ExecutionTime 表示从计算开始到该步结束之后消耗的总时间 ClockTime 表示从计算开始到该步结束之后消耗的CPU 时间,仅显示整数。依据前后两个计算时间步的差以及算例设置的总时间(或总时间步数),大致可以算一下整个计算机计算该算例所需要的总时间 当然其他的求解算例输出信...

24 此处涉及到 OpenFOAM 求解器源代码中极为常用的 runTimeMechanism (运行时选择机制) 每个湍流模型的参数都 在每个湍流模型的代码中并且具有一个默认值。printCoeffs 开关如果设置为 on 的话,这些参数的值会被输出到终端。它们以子字典的形式被输出,我 们会看到每个模型的名字后面都加上了 Coeffs ,例如 k...

The utility is implemented as a runtime postprocessing object derived from the built-in fvMeshFunctionObject and logFiles classes. It integrates the normal velocity through a specified face zone at each required time step and writes the result to a file, as well as prints in on the screen....
