Hi everyone,

I have a problem related to assign value in OpenFOAM, the detail is as follow:

in interFoam solver, two variable alpha1 and alpha2 are defined as:
volScalarField& alpha1(mixture.alpha1());
volScalarField& alpha2(mixture.alpha2());

Now, I declare a variable with same type as:

volScalarField H
(
IOobject
(
"H",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
alpha1
);

to compute something.
After computation, I want to reassign value of alpha1 by H as:
alpha1 = H;
However, my assignment did not work since when I check the printed output of two files alpha1 and H, the value in same cell mesh are not identical as shown in the attachement.

Could anyone help me to explain the reason for that.

I thank you very much in advance.
