Add a viscoelastic property to transportModel
 

Hi, Formers:
I want to combine the "viscoelasticFluidFoam" with "InterFoam" . At this stage, I have met a question about "transportModel.H". the file just include the "viscosityLaw.H" or "viscosityModel.H". I want to add a viscoelastic phase like using the Giesekus model. Just including the "viscoelasticLaw.H" or "viscoelasticModel.H" to the transportModel.H is not enough, the viscoelasticModel return "tau", how can I do with the question? Please tell me in details, your patience always be appreciated!

can someone help me?:confused:
