POLYFLOW 3.9, to be released this winter, is built on five major pillars: adaptive meshing, non-conformal meshing, numerous enhancements and extension of viscoelastic models, elasticity-based remeshing, and a new user-friendly environment. In addition, numerous enhancements have been incorporated into the code.

Adaptive meshing now serves to further extend the remarkable deforming mesh capabilities of POLYFLOW. Blow molding, thermoforming, and glass forming applications, where the deformations of the initial parison, gob or preform are large, will all benefit from this automatic mesh refinement. Based on remeshing criteria specified by the user, the solver adjusts the finite element mesh to capture the geometric details while maintaining accurate results. Automatic mesh refinement close to overlapping borders also improves the accuracy of results in simulations that use the mesh superposition technique.

With the non-conforming mesh, the user can generate a mesh on simple sections of a die, for example, before combining them within the graphical user interface (GUI). Using this new capability, a complex window profile die can now be set up more quickly than before for a similar result quality. Finally, the new environment layer incorporates GAMBIT, POLYFLOW, POLYDATA, and postprocessing tools within the same interface. It helps organize the user's simulations, removing the burden of dealing with numerous directories and a myriad of files.
