是的，在新版除了createFields.H没了，fvCFD.H都没了。变量都在class里面初始化，比如VoFSolver。H：
class VoFSolver
:
public fluidSolver
{
protected:
// Phase properties
//- The compressible two-phase mixture
autoPtr<VoFMixture> mixturePtr_;
VoFMixture& mixture_;
//- Name of the alpha convection scheme
const word divAlphaName;
//- Phase-fraction flux Courant number
scalar alphaCoNum;
// Kinematic properties
//- Velocity field
volVectorField U_;
//- Volumetric flux field
surfaceScalarField phi_;
