The COMPUPLAST® VEL™, Material Properties module is the main VEL™ module. Material Properties is used to build and maintain a database of materials that can be used for simulation in all of the other VEL™ Modules. It has utilities to fit viscosity versus shear rate data to the available viscosity models and then store the information to the Material Database. The Viscosity Fitting utilities can fit viscosity data to the most popular viscosity models with any necessary corrections. The data can be input by hand, read in from a text file or simply using Windows® “Copy and Paste” functions from a spreadsheet. Once the data have been fit to a model, the program saves the material parameters in the Material Database.
