Boundary Condition definition for Tensorial Fields and viscoelastic flow simulation

titio · February 4, 2009, 06:56

Hi everybody,

I am currently trying to model the flow of a viscoelastic fluid using a differential constitutive model. Right now I am having difficulties on how to define the boundary conditions for a tensorial field. Can I do it the same way as I do it for a scalar and vectorial field?

Also, for viscoelastic flow I have some doubts on how to define the boundary conditions, in particular with walls. Someone have some idea on how to do it, or can give the reference of some work where they study this questions.

To define the boundary conditions for a tensorial field, look in $FOAM_TUTORIALS/simpleFoam/pitzDaily/0/R
