请问fvm::Su 和 fvc::Su 的区别,我知道source term function 有 Su,Sp,Susp对应的分别是显示离散,隐式离散,显示/隐式离散,但是如果是fvc::Su 和 fvm::Su 区别是什么? fvm::Sp 和 fvc::Sp 呢?
fvm::Su
fvc::Su
fvm::Sp
fvc::Sp
fvm返回的都是矩阵,矩阵又分为矩阵系数和矩阵源项(右边那一行)。fvm::Su返回矩阵的源项,fvm::Sp返回矩阵系数。fvc返回的都是场,比如标量场。
fvm
fvc
你的问题:fvc::Su(T, k)返回T,fvm::Su返回矩阵源项。fvm::Sp返回矩阵系数, fvc::Sp(T, k)返回Tk。fvc::Su(T, k)=T。
fvc::Su(T, k)
T
fvc::Sp(T, k)
Tk
fvc::Su(T, k)=T
