The VEL™ , Profile Die module is used for the precise analysis and design of profile cross-sections of arbitrary shape. Based on the Finite Element Method (FEM) of mathematical analysis, the program can provide very detailed information about the flow through the profile shape. The pressure drop, velocity distribution and shear stress distribution are just some of the flow characteristics that can be evaluated. More importantly, the designer or process engineer can use this module along with the COMPUPLAST® profile die design procedure to reduce product development time by 50% or more. The user friendly, intuitive, interface allows you to create, test and optimize many designs quickly and efficiently.

The VEL™ , Profile Die module has been developed with the extrusion process engineer in mind. From simple square or round rod profiles to complex window profiles, this module is being used by profile extrusion companies, world wide, to make new designs or optimize existing ones. Among the new features and improvments is the ability to simulate wall slip effects which make the program even more accurate in PVC applications. From a process standpoint, this module has been used to investigate the effects of changing materials or to determine the maximum extrusion speed for process optimization.

The VEL™, Profile Die module features:
- improved graphical design interface
- local mass throughput/area integration
- 'slip at the wall' boundary condition
- improved image/results saving capability
- improved Material Database interface
