The geometry was the 4:1 plane contraction. This is a well studied geometry in viscoelastic fluid flow research. More details about the model or parameters used can be found at: *** L.M. Quinzani, R.C. Amstrong, R.A. Brown, Birefringence and laser-Doppler velocimetry (LDV) studies of viscoelastic flow through a planar contraction, J. Non-Newtonian Fluid Mech. 52 (1994) 1-36. *** This is only an illustrative case for the Oldroyd-B constitutive model. Therefore, there are not more details published until now for this model using this geometry and viscoelasticFluidFoam solver.
