VEL™ 2D FEM Module™: Detailed Flow Channel Analysis

The COMPUPLAST® VEL™, 2D FEM module™ is used for the precise analysis, optimization and/or design of 2D flow channels of arbitrary shape. Based on the Finite Element Method (FEM) of mathematical analysis, the program can provide very detailed information about a flow field. Recirculation regions (vortices) or stagnant flow regions which result in excessive residence time for the material can be easily observed.

Areas of excessive shear stress, which can lead to surface or interfacial defects can be investigated. More importantly, the design or process engineer can use this module to ensure that the design of the flow channels avoids these types of problems. The user friendly, intuitive, interface allows you to create, test and optimize many designs quickly and efficiently.

VEL™ 2D FEM Module™: Versatile Tool for Extrusion Design

The VEL™, 2D FEM module has been developed with the extrusion process engineer in mind. From wire and cable coating to coextrusion die design, this module is used to provide valuable design information in virtually any extrusion process. Equipment Manufacturers use the module to analyze and design equipment for commercial applications in a wide area of extrusion including, pipe and tubing, cables, fiber spinning, blown film, blow molding, flat sheet and film with up to 10 layers. From a process standpoint, this module has been used to investigate various phenomena such as “shark skin”, “die drool”, “extrudate swell” and “interfacial instability”. The versatility and ease of use have truly made this module a valuable CAE tool.
