POLYFLOW - Simulation of coextrusion with transport variable and adaptive meshing
Simulation of coextrusion flow with transport variable and adaptive meshing. How to start the calculation, considering the fact that a steady solution is of interest.
The following steps are :
- dependence of power index with respect to the transport variable.
The following strategy is suggested, based on two steps:
- evolution on sliping, with keyword CONVELOC in p3rc file, and a late adaptive meshing (so that it is not yet activated)
- start from the former result, with slipping being replaced by vanishing vleocity, velocity and transport included in the precision evalution, and adaptive meshing activated.
