hello guys,
I am using compressible interfoam solver. In one of my subroutine I used the code shown below in twoPhaseMixtureThermo.C



Code:
Foam::tmp<Foam::volScalarField>
Foam::twoPhaseMixtureThermo::interfaceArea() const
{
    
    // return the interfacial area based on model for interfacial area
    // returns dimensions Area

    // model based on regular volume cells, taking the largest cut area
    // as maximum for area, linear increase and decrease with alpha
    const surfaceScalarField& nHatf = db().lookupObject<surfaceScalarField>("nHatf");
    volScalarField interfaceArea = reconstruct(nHatf());
        

    return tmp<volScalarField>
    (
      interfaceArea
    );

}

And i got error message that reconstruct is not declared


so I changed code as shown below
volScalarField interfaceArea = interfaceProperties::nHatf();


error:
Code:
twoPhaseMixtureThermo.C:138:65: error: conversion from ‘Foam::tmp<Foam::Field<double> >’ to non-scalar type ‘Foam::volScalarField’ {aka ‘Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>’} requested
  138 |     volScalarField interfaceArea = interfaceProperties::nHatf() * alpha1();
      |                                    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~


Can anyone help me with this
Thanks in advance
