Hi Guys,

I changed one library in

PHP Code:

 src/transportModels/twoPhaseProperties/alphaContactAngle/dynamicAlphaContactAngle 


to

PHP Code:

src/transportModels/twoPhaseProperties/alphaContactAngle/mydynamicAlphaContactAngle 


.
I changed the related files in Make directory and also wmake libso works fine and library is up to date. when I add my library

PHP Code:

libmytwoPhaseProperties.so 


to controldict, and I run the case with mydynamicAlphaContactAngle, error message comes:

PHP Code:

 --> FOAM FATAL IO ERROR: 
Unknown patchField type mydynamicAlphaContactAngle for patch type wall

Valid patchField types are :
.... 


Can anyone helps me?
thank you in advance for any comment.

Hi,

well... you've just renamed folders, corrected files in Make folder. But did you change actual source code? Especially this parts of dynamicAlphaContactAngleFvPatchScalarField.C

namespace Foam
{
    makePatchTypeField
    (
        fvPatchScalarField,
        dynamicAlphaContactAngleFvPatchScalarField
    );
}

Wasn't able to guess it from your post.

Thank you for reply.
Yes I changed all needed parts in .C and .H files. but I do not know what is wrong.

[alexeym]

Can you post modified code?

I attached the my dynamicAlphaContactAngle and Make.
Thanks

Hi,

it'll be better if you also attach test case but right now I've found this:

    //- Runtime type information
    TypeName("dynamicAlphaContactAngle");

in mydynamicAlphaContactAngleFvPatchScalarField.H. I think it'll be better to change it to

    //- Runtime type information
    TypeName("mydynamicAlphaContactAngle");

It works now . Thank you very much.

But I changed the whole "dynamics" globally to "mydynamic", I don't know why it did not work.

Hi,

in continue of above modification, I tried to add sigma to the contact angle definition in mydynamicAlphaContactAngleFvPatchScalarField.C as :
[CODE] return theta0_ + (thetaA_ - thetaR_)*sigma() *tanh(uwall/uTheta_);/CODE]

I though if I add
[CODE]tmp<volScalarField> sigma() const;/CODE]
to the mydynamicAlphaContactAngleFvPatchScalarField.H, I define the sigma. but this one does not work. So, what should I do to be able to use sigma in first part?

Thank you for your great comments.

Hi,

1. What is sigma? Does it depend on location or it's just a constant?

2. What do you mean by "but this one does not work"?

3. And finally what's the implementation of sigma method you've defined?

[gooya_kabir]

thank you. Answering your question caused me to understand my problems which now I'm trying to solve. for example sigma is interfacial tension on the surface.

I will come back if I could not
