Simulate coex layer instability.


Compuplast North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. , Mississauga, Ont., is about to introduce what it says is the first commercial simulation software Simulation software is based on the process of imitating a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually running the program.  that automatically analyzes coex film, sheet, or pipe dies for potential interfacial instability based on die geometry and material flow properties. Wave-type instability is related to viscosity and elongational properties of resins in adjacent layers at the point where they merge in the die. Zigzag instability occurs at the exit of the die where stress and speed are high.

A beta version of Interfacial Instability Analysis was exhibited at the recent International Plastics Fair in Tokyo and the commercial release will be at NPE NPE NullPointerException (Java)
