老师们好,请问在表示通量phi时,fvc::flux(U)和fvc::interpolate(U) & mesh.Sf()有什么区别?
@疏影横斜水清浅 没区别
@dzw05 我是这么使用这个通量的,surfaceScalarField phiVp = fvc::flux(Vp); 计算时是fvm::div(phiVp, C),然后使用求解器时要求我设置div(interpolate(Vp),C)的格式。如果使用surfaceScalarField phiVp = fvc::interpolate(Vp) & mesh.Sf();要求我设置div((interpolate(Vp)&S),C)的格式,所以我想问他们的区别。 谢谢老师
