POLYFLOW - fibre spinning and pulltrusion for a viscoelastic flow without symmetry
|
The definition of a free surface flow with take-up velocity and one symmetry plane or less does not enable the constraint on global displacement. What can be done here ? An easy workaround conssits of defining the flow with: - zero froce at the exit - a submodel for imposing the take-up velocity at the exit of the calculation domain. N.B. evolution on the take-up velocity is also available here; and appropriate scheme can be defined on the take-up velocity. |
