Hi friends
I've just learnt the openFoam. I solved a special problem with a newtonian fluid(water). Now, I want to solve it with a viscoelastic fluid by Oldroyd-B model. Could you please help me to do it step by step? (you know, I don't know any thing about it!)

Thanks every body

Hi,

You can look to the viscosity models already in OpenFOAM, in:
..your openfoam directory.../src/transportModels/incompressible/viscosityModels
In a shell, you can find them by typing:
/src/transportModels/incompressible/viscosityModels

Now, based on your needs you can create your new viscosity model similarly as a new library.

If difficult for you, you can also try simply at the Top-level code (directly in the openfoam solver files .H & .C)

Good Luck !

regards,
T.D.
