对某文章关于piso循环的一段话不太明白
-
The solution for pressure equation utilizes the PISO (pressure implicit with split operator) based PIMPLE method, together with a conjugate gradient methods for coupled mass and momentum conservation equations, which is specifically suited to transient flow.
文章用的是openfoam
里面提到的conjugate gradient methods这个该怎么解读 -
conjugate gradient methods
这个是矩阵求解器啊。PBiCGStab,PBiCG这种的。

@东岳 对,后来查看了一下userguide 中的solver部分,里面PCG的全称是preconditioned conjugate gradient,就一下明白了
