request for volScalarField from objectRegistry failed

[李东岳]

在寻找对象的时候，初始化成员这样写的话：

rhoc_(mesh.time().lookupObject<volScalarField>("rhoc")),
或者
rhoc_(mesh.time().db().lookupObject<volScalarField>("rhoc")),
等等等，报错如下

--> FOAM FATAL ERROR: 

    request for volScalarField rhod from objectRegistry QMOM failed
    available objects of type volScalarField are
0()

更改为

rhoc_(mesh.lookupObject<volScalarField>("rhoc")),

即可，这样寻找的对象注册体为region不是是类型。

--> FOAM FATAL ERROR: 

    request for volScalarField rhod from objectRegistry region0 failed
    available objects of type volScalarField are
available objects of type volScalarField are

@李东岳 李老师，在使用openFOAM-V2006版本的buoyantBoussinesqFoam求解器，出现如下报错：
--> FOAM FATAL ERROR:

request for basicThermo thermophysicalProperties from objectRegistry region0 failed
available objects of type basicThermo are

0()

请问是什么原因呢，我的constant 和0文件与tutorials一致，还是报错。
