Hello,

I have compiled solidParticleFoam solver, which uses solidParticle libraries. Then modified solidParticle library in order to add another dimensionedScalar in particleProperties dictionary. And also modified the solidParticleFoam accordingly.

I made the following changes in respective files in the solidParticle library (red color denotes the added code). It compiles without errors. However, when I run the solver, then I get an error, which I believe is about the particleProperties dictionary. What do you think?

mySolidParticleCloud.C

Foam::mySolidParticleCloud::mySolidParticleCloud
(
    const fvMesh& mesh,
    const word& cloudName,
    bool readFields
)
:
    Cloud<mySolidParticle>(mesh, cloudName, false),
    mesh_(mesh),
    particleProperties_
    (
        IOobject
        (
            "particleProperties",
            mesh_.time().constant(),
            mesh_,
            IOobject::MUST_READ_IF_MODIFIED,
            IOobject::NO_WRITE
        )
    ),
    rhop_(dimensionedScalar(particleProperties_.lookup("rhop")).value()),
    e_(dimensionedScalar(particleProperties_.lookup("e")).value()),
    mu_(dimensionedScalar(particleProperties_.lookup("mu")).value()),
    temp_(dimensionedScalar(particleProperties_.lookup("temp")).value())
{
    if (readFields)
    {
        mySolidParticle::readFields(*this);
    }
}

mySolidParticleCloud.H

// Private data

        const fvMesh& mesh_;

        IOdictionary particleProperties_;

        scalar rhop_;
        scalar e_;
        scalar mu_;
    scalar temp_;

...

            inline scalar rhop() const;
            inline scalar e() const;
           inline scalar mu() const;
        inline scalar temp() const;

mySolidParticleCloudI.H

inline Foam::scalar Foam::mySolidParticleCloud::rhop() const
{
    return rhop_;
}

inline Foam::scalar Foam::mySolidParticleCloud::e() const
{
    return e_;
}

inline Foam::scalar Foam::mySolidParticleCloud::mu() const
{
    return mu_;
}

inline Foam::scalar Foam::mySolidParticleCloud::temp() const
{
    return temp_;
}

And also I added the following line into the particleProperties file in constant directory:

FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    object      particleProperties;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

rhop rhop [ 1 -3  0  0  0  0  0] 1000;
e    e    [ 0  0  0  0  0  0  0] 0.8;
mu   mu   [ 0  0  0  0  0  0  0] 0.2;
temp    temp    [ 0  0  0  1  0  0  0]    283.15;

// ************************************************************************* //

Then I run my solver mySolidParticleFoam. I get the following error:

#0  Foam::error::printStack(Foam::Ostream&) in "/opt/openfoam200/platforms/linuxGccDPOpt/lib/libOpenFOAM.so"

Alright, I solved the problem.
After compiling solidParticle library, it seems that in this case I have to compile mySolidParticleFoam, as well. Even if I did not change anything in the solver itself.

This confuses me a little because in some cases it works fine even though I don't recompile the solver after making changes in mySolidParticle.C file

Hello! Now I am using solidParticleFoam right now. I have a problem with it. In 0/lagranglan/defaultcloud/d
FoamFile
{
version 2.0;
format ascii;
class scalarField;
location "0";
object d;
}

2
(
2.0e-3
2.0e-3
)
why the diameter doesn't have a unit.
If I want to simulation the process in which particle dissolution with a fixed speed. And the diameter becomes small with time. What should I do. Modify solidParticle. C or something else.
