freestreamFvPatchField< Type >:This boundary condition provides a free-stream condition. It is a 'mixed' condition derived from the inletOutlet condition, whereby the mode of operation switches between fixed (free stream) value and zero gradient based on the sign of the flux 压力进口条件: 1: ...
在OpenFOAM中,边界条件(Boundary Conditions, BCs)是模拟流体流动时,对物体表面施加的一种条件,用于定义流体在计算域边界上的行为。边界条件的设置对模拟结果的准确性至关重要,需要根据具体的模拟需求和问题来选择合适的边界条件。 OpenFOAM中常用的边界条件类型 fixedValue 描述:指定流体变量的恒定值。 使用场景:如气...
class Foam::mixedFvPatchField< Type > This boundary condition provides a base class for 'mixed' type boundary conditions, i.e. conditions that mix fixed value and patch-normal gradient conditions. The respective contributions from each is determined by a weight field: xp=wxp+(1−w)(xc+...

A C++ class named magPhiMixedFvPatchField describing the newly derived boundary conditions is defined based on OpenFOAM libraries. The new open-source solver labelled as magneticMultiRegionFoam, for the simulation of static magnetic field with multi-regions, based on FVM in the OpenFOAM framework ...
