COMPUPLAST® VEL™ NEWS



Virtual Extrusion Laboratory™
K Show Software News


COMPUPLAST® will introduce the latest news in Virtual Extrusion Laboratory™ (VEL™) 6.4 version and planes and innovations planed for version VEL™ 6.5.
There were done the big improvements in several modules, here is the list of the main ones:

General News in Common Environment and the Main Panel
− The program data folders have been moved to a new folder called
“…\My Documents \CompuplastVELDataFolders”
− If the currently used data folder does not exist when a module starts the program shows a panel to define a new working folder.
− There is a possibility to run a diagnostic program showing various diagnostics data necessary for running VEL™.
− Some of the programs can be run in Japanese and German language.
− The materials are listed in trees in all modules.
− The checking parameters can be defined in 3 levels (general values, for a group and for a material).
− The layout of some programs has been changed to a more compact one-window tree structure; geometry, project and material editing as well as post-processing in one window. Also the Calculator is available there. The tree structure contains always a panel for user comments dealing with a particular item.
− For changed programs some of variables can be described by a single value or by an equation.
− Each new program contains a panel “Material(s) and process conditions”. In this panel the materials and initial boundary conditions can be set in the same way.
− From each changed program all the pictures (fields), numerical results, graphs and summaries can be exported.
− For definition by equation there is available a panel containing all relevant variables, which can be used for the equation definition.



Material Properties module™ and Extrusion Calculator™
− The layout of the material properties editing and Calculator environment has been changed to the tree structure
− The list of checking parameters has been extended.
− During the material editing the Calculator is available for current material data setting.
− New calculations were added into Calculator



Extruder module™
− There was improved the calculation of a starving extruder

− A newly created extruder is set by a wizard predefining basic dimensions
− During Extruder dimension editing the program shows screw cross-section areas.
− In the barrel definition a position of evacuation hole, material modification position and grooved barrel presence can be defined.
− There can be set the roughness of barrel and screw surface under the hopper. This can be used for friction coefficient calculations.
− The throat geometry is better defined.
− The zone under the hopper(feed zone) is distinguish from the other temperature zones
− The user can enter grooved characteristics and they are used for the calculation.
− The calculation of the grooved feed section was improved.
− There were added some mixer types and also channel types; mainly for waving profile channels.
− Entering of complete barrier section is allowed now
− During editing of the channel shapes, the program shows pictures of currently edited shapes for easy editing
− In last VEL 6.4 version there are all solvers used in previous versions (3 solvers are available now).
− Friction coefficients can be entered as a value or defined as an equation
− The program calculates newly elongational rates and elongational stresses along the screw.
− For mixing elements with barrier, the program allows to visualize values exactly in position of the barrier.
− The numerical results and project summaries can be exported into Excel file.


3D FEM module™
− The solver was separated from the Studio performance
− The solver can be run independently of the graphic Studio in a batch
− All operations such as picking, zooming were substantially accelerated and improved
− The program allows defining the metal of the die forming the flow domain; the calculation of the heat transfer on this metal is possible.
− The solver recognizes 32 bit and/or 64 bit Windows system and can be run effectively on these systems.
− The initial temperature can be defined as a profile
− The program shows histograms of relevant variables mainly on surfaces
− In post-processing the user can define more complex variables to review
− The number of supported formats for grid import was increased
− The software can be used also for the aluminum extrusion
− Preprocessing operations simplified and enriched, resulting in significant gain in speed and user comfort.
− Many new types of boundary conditions added including adiabatic and HTC walls, slip boundary conditions or inlet temperature profile. The BCs can be arbitrarily oriented.
− Display options and settings for entity appearance simplified and made more consistent
− Major improvements were made on solver. The efficient, parallelized solver automatically detects Windows version (32 to 64 bit) and runs an optimized code.
− Solution of temperatures stabilized to handle large temperature gradients. The program allows defining the metal of the die forming the flow domain; the calculation of the heat transfer on this metal is possible.
− The software now allows to solve the aluminum extrusion
− The solver can run in a batch mode and also allows to journal the solution progress.
− In post-processing the user can define more complex variables to review.
− The program shows histograms of relevant variables
− The customizable reporting added so that automatic problem identification is possible.
− AVI file creation now supported through XML routines.


2D FEM module™
− Coextrusion calculation was improved by predefining super-elements which are split by the program during the calculation of the interface.
− Dxf import was improved.
− There was generalized a way of setting some variables defining the grid.

Profile Die module™
− During cross-section editing the program allows simultaneous visualization of final shape
− Dxf import was improved; mainly importing inner boundaries.
− There was generalized a way of setting some variables defining the grid.
