IOobject::groupName("omega", alphaRhoPhi.group()) 这句话的意思是?
-
注册omega如下,有地方不理解:
omega_ ( IOobject ( IOobject::groupName("omega", alphaRhoPhi.group()), this->runTime_.timeName(), this->mesh_, IOobject::MUST_READ, IOobject::AUTO_WRITE ), this->mesh_ )
IOobject::groupName("omega", alphaRhoPhi.group()) 知道是定义omage的name,但是 后面这个alphaRhoPhi.group(),是起到什么作用呢?
如果我定义成:
omega_ ( IOobject ( "omega", this->runTime_.timeName(), this->mesh_, IOobject::MUST_READ, IOobject::AUTO_WRITE ), this->mesh_ )
会有什么效果无法实现?
