ANSYS, Inc. Release Notes
The new features in ANSYS POLYFLOW 14.0 are as follows:
ANSYS POLYFLOW can use Named Selections from ANSYS Meshing.
ANSYS POLYFLOW can read meshes created using the Assembly Meshing group in ANSYS Meshing or the CutCell mesher in TGrid.
You can create user-defined templates via the UPDT button to parameterize the values for the absissa and/or ordinate of:
multi-ramp functions of time or S (for evolution problems), when the multi-ramp functions are applied on a parameter of a model (e.g., fac, vn, cp)
multi-ramp functions of X, Y, or Z coordinates when defining the average temperature, the average concentration, the initial fluid fraction for volume of fluid (VOF) problems, or the initial thickness distribution of films or the parison for shell models.
ANSYS POLYFLOW allows you to define force-driven mold motion for shell surface parisons, with limitations on the maximum displacement.
A new heuristic technique has been implemented for defining the order of elimination of the equations in the AMF linear solver (which is the default solver in ANSYS POLYFLOW 14.0). This technique can lead to significant reductions in CPU time and memory requirements under certain circumstances. Improvements should be observed for fixed and deforming domain simulations when the mini-element interpolation is used. The new heuristic technique does not make any difference when pressure stabilization is enabled (linear interpolation of velocities).
ANSYS POLYFLOW provides further options for decoupling the calculation of various fields:
For internal radiation, you can decouple the calculation of the velocities, irradiance, and/or temperatures.
For transport of species, you can decouple the calculation of the velocities and species.
ANSYS POLYFLOW allows you to export temperature and thickness data to results files that can be used for further simulations in ANSYS Mechanical.
ANSYS POLYFLOW allows you to simulate contact release (i.e., the detachment of a free surface that has come into contact with a wall) for a 3D or shell model, as part of a blow molding or thermoforming simulation.
ANSYS POLYFLOW allows you to convert .poly files written by ANSYS Meshing to the POLYFLOW format.
ANSYS POLYFLOW can read and recognize 1D and 2D PMeshes exported from ANSYS ICEM CFD and ANSYS Meshing.
POLYFLOW allows you to convert a mesh into a sliceable mesh in POLYDATA, so that you can employ certain remeshing techniques that are otherwise incompatible with the mesh or easily modify aspects of an existing sliceable mesh.
A POLYFLOW system can be connected to an ANSYS Mechanical system in Workbench, so that you can transfer thickness and temperature data.
A series of templates are available. These templates are in the form of Workbench projects, and each contains a complete simulation from geometry to postprocessing, including design parameters. You are thus able to connect your own geometry, adapt the design parameters in ANSYS DesignXplorer, and simply update the project. A predefined report is then automatically created in ANSYS CFD-Post. These templates currently cover the main applications of POLYFLOW: extrusion, blow molding, and thermoforming.
POLYFLOW documentation is available via the Help pull-down menu in the various POLYFLOW applications, as well as the Help chart button in ANSYS POLYMAT and ANSYS POLYCURVE.
For a boundary that experiences both incoming and outgoing flows (e.g., an outlet with backflow) as part of a nonisothermal simulation, ANSYS POLYFLOW allows you to impose a temperature on the flow that enters the domain via the Incoming fluid temperature thermal boundary condition.
The view in the ANSYS POLYFUSE Graphics Display window can be manipulated via a graphics toolbar (which replaces the View Options panel), as well as shortcut keys.
A more user-friendly graphical user interface has been introduced for ANSYS POLYMAT and ANSYS POLYSTAT. The updated GUI provides a higher quality display of the results and allows an interactive manipulation of graphical objects.
POLYFLOW provides access to POLYFLOW project templates, which are Workbench project files that you can modify in order to quickly and easily set up your own problem. These templates include blow molding, extrusion, and thermoforming problems.
