Solver Enhancements for 2019
Enhancements have been implemented to improve the performance of analysis solvers, and to provide you with better solutions.
Moldflow Rotational Diffusion model parameters
The Moldflow Rotational Diffusion model parameters have been adjusted. Autodesk Moldflow Insight (AMI) 2019 now predicts a stronger fiber part alignment in the part length direction, and a weaker alignment in the part width direction, at the part surface. For normalized thicknesses this effect can be noticed at thicknesses less than 0.2 and greater than 0.8. This result provides closer agreement with experimental data compared with AMI 2018.2 results.
Fountain flow effect on fiber orientation
Incorporating fountain flow into the fiber orientation prediction produces a result that has good agreement with experimental data in the skin layers. Warpage prediction results are also influenced by this improvement. This modification has little effect on the internal orientation results.
