The CAEFF software engineering group is developing simulation tools capable of predicting final properties for a given polymeric material in an industrial fiber or film process. CAEFF models will ultimately incorporate the entire spectrum of fiber and film process stages, which include melting and mixing, filtration, forming, external flow under quench conditions, and drawing and take-up.

The underlying C++ framework for this software provides a modular structure which allows rapid integration of new models as they are developed. The user designs a simulation composed of one or more modules representing process stages. The user then customizes the model, via user-friendly interfaces, with the polymer and process information. All the models may be executed as one complete process, and results are provided both in graphical displays and with the capability of storing output data in textual form for use with other visualization packages.

The prototype code incorporates filtration forming, external flow under quench conditions and drawing, applied to fiber melt-spinning. The user can set a variety of process and material parameters. Default material parameters for several polymers can be read in from the CAEFF polymer database.

Visualization plays a prominent role, providing a user-friendly means for initializing, monitoring, and post-processing simulation output. The process stages are integrated using a component-based design so that configurations representing all or part of a process stage can be easily swapped in and out. The software that implements these process models is primarily written in C++, though C, FORTRAN, and MATLAB are also used. Generative programming techniques are used to overcome degradation in the performance and memory which is often associated with the C++ language.
