Are you involved in film blowing or stretch tube production? Are you facing challenges with bubble stability? Would you like precise data on temperatures, velocities, thicknesses, and other physical properties throughout the entire bubble length? The VEL™ system includes a specialized module for simulating bubble behavior during the film blowing (or tube stretching) process. This module enables you to: Design the bubble’s shape Optimize temperature development both along and across the bubble Estimate thickness, velocity, deformation, stress, and curvature Identify stability problems We are excited to...

16. 6. 2025

Compuplast’s complex and precise 2D and 3D finite element calculations are powerful CAE tools. However, in many situations, a faster estimate is needed — and often sufficient. That’s where simple 1D solvers can provide essential information for your redesign steps. The VEL™ 7.0 Extrusion Calculator is a set of lightweight CAE tools. It is simple to use, fast to solve, and easy to post-process, yet can still support the design of complex extrusion tooling. This calculator can be used as a socket...

Periodicity in VEL™ 7.0 3DFem module

Technical articles
16. 6. 2025

Almost any type of extrusion die can be solved using the Compuplast VEL™ 7.0 3DFem module, including popular spiral mandrel dies and/or flat spiral dies. However, the geometry of these die types is periodic. Therefore, it is essential to take advantage of periodicity to speed up the solution process.Why solve the entire model if, for example, it contains 12 identical periodic sections? Why not solve just one of them—saving both time and memory? New in version 7.0, we have introduced support...

21. 9. 2022

This paper describes a case study dealing with the development of a three-layer product on a feed-block coextrusion system. The problems or phenomena that occurred during the product development experiments are explained via flow simulation and the rheological properties of the materials used. The results of the study are compared with real film samples produced during the development Article can be downloaded here. ...

Technical articles
21. 9. 2022

Flow inside a die can be simulated by most of Compuplast VEL™ modules. An axi-symmetric or planar flow inside a die can be simulated by using the 2DFem module, any profile die can be simulated by the 3DFem module, some profile dies and designed profile dies can be simulated by using the Profile die module, flat dies, spiral dies, flat spiral dies (stackable dies) or cross-head dies can be simulated by using the appropriate module. In all these modules the...
