The Viscosity result shows the viscosity of the polymer at the time the results file was written.
The viscosity of a material is described as a measure of its ability to flow under an applied pressure.
This result is generated from a Fill analysis using 3D analysis technology.
The viscosity of polymers is dependant on temperature and shear rate. In general, as the temperature and shear rate that the polymer experiences both increase, the viscosity will decrease, indicating a greater ability to flow under a given applied pressure. The results are calculated from the viscosity distribution across the molten (above transition) part of the cavity.
For a Fill analysis using 3D analysis technology, viscosity is calculated for each tetrahedral element or node throughout the model. The values calculated by the program are the actual viscosity values for the tetrahedral elements, or nodes and represent a real case injection molding scenario. The 3D viscosity result is more accurate than the fast algorithm or the finite difference algorithm because actual values are being determined at each node of the solid model.
