Dear FoAMERs'

There is a variable named as alpha1_ in one of the derived sources named as "solidificationMeltingSource" defined in "solidificationMeltingSource.H

volScalarField alpha1_;

also in "solidificationMeltingSource.C" it is defined as IOobject

alpha1_
(
IOobject
(
name_ + ":alpha1",
mesh.time().timeName(),
mesh,
IOobject::READ_IF_PRESENT,
IOobject::AUTO_WRITE
),
mesh,
dimensionedScalar("alpha1", dimless, 0.0),
zeroGradientFvPatchScalarField::typeName
),

when I am using the source through "buoyantPimpleFoam" solver/application,

the swakexpression cannot recognize alpha1 variable.

But as alpha1 is a IO object in output files the field of alpha1 is written as output, here it name is printed as "sMS1:alpha1" ( sMs1 is a name provided to the set of input variables in contant directory in fvOptions file)

by any way swak4Fom/functions/coding please guide me so that I can calculate some derived quantities using this field of alpha1 for every time step.

I am not a expert in C language so please instruct me in detail.

Anxiously waiting for a any kind of help

Regards.

How to define a global variable in application such that the src/....../derived sources can update it

Any new scalar created in application or meltingandsolidificationsources they are not global and we cannot transfer the information from one (application or src ) to other (src or application ).


I am very new to C++ and openfoam programming kindly help...
