Dear Friends,

I would like to have information about numerical simulation of viscoelastic flows by using finite differences. In particular, we are interested in numerical methods for free surface flows. Please, send me some references.

Thank You Very Much and Good Luck for All.

Dear Dr. Ferreira,

Are you only interested in the finite difference method?

On the other hand, the finite element method has been widely used to solve viscoelastic flows, including free surfaces. Please check on the work by M. Crochet and others. This work has been commercialized in the finite element code POLYFLOW.

Please let me know if you need more information.

Regards,

Eric Grald

Hi Dr. Eric Grald,

Thank you for your help. Yes, I am interescted only in the finite difference method. Please, I need information such as thesis and papers. If you have any information, let me know.

Best Regards,

Valdemir.

Hi friends,

I am student in fluid mechanics. I would like to know information about boundary conditons for Oldroyd-B fluids with free surface.

Thank you very much.

Luciane.

Hello Luciane,

I'm Thierry Marchal the Product Manager of Polyflow. The Oldroyd-B model is one of the differential viscoelastic model available in Polyflow together with the Giesekus-Leonov, Phan Thien-Tanner, FENE-P, White-Metzner and Maxwell models. All of them can be considered in 2D and 3D, isothermal and non-isothermal (though full 3D non-isothermal simulation can be time consuming). As mentioned previously by Eric Grald, we are using a finite element technique to solve the equations. These simulations can be combined with free surface(s) where the kinematic condition (Vn = 0, Fn = Fs = 0) is specified along the free border.

Please contact me by email describing your specific requests in more details in order to further discuss this topic.
