Press Release Summary:
Moldflow Plastics Insight v6.1 features double refraction (birefringence) prediction capabilities to help designers of optical parts eliminate lens defects. Plastics design analysis software includes 3D ANSYS and 3D ABAQUS interfaces, supporting export of 3D overmolding, 2-shot sequential overmolding, and microchip encapsulation models. Also included, customer-driven interfaces to Nastran and Patran allow for export of key plastics material data and analysis results.
Original Press Release:
Moldflow's Plastics Simulation Software Able to Predict Double Refraction In Lens Applications
Moldflow Corporation announced the release of their plastics design analysis software, Moldflow Plastics Insight (MPI) 6.1. MPI 6.1 now has the ability to predict birefringence (also known as double refraction), which is a phenomenon that causes optical defects in lens applications. This will allow designers of optical parts to be able to eliminate one of the major causes of lens defects in applications ranging from automotive lighting to magnifying glasses used to inspect medical x-rays to display screens on cell phones.
Enhanced 3D ANSYS and 3D ABAQUS interfaces now support the export of 3D Overmolding, 2-shot Sequential Overmolding, and Microchip Encapsulation models. The 3D ANSYS interface also enables the export of a 2-layer, aggregated 3D mesh with results, which improves the efficiency of structural analyses completed in ANSYS. MPI 6.1 offers new customer-driven interfaces to Nastran and Patran for the export of key plastics material data and analysis results, thereby improving the accuracy of subsequent stress analyses.
MPI 6.1 features a parallel solution method on shared memory multi-processor (SMP) systems, which speeds up 3D Warp analyses by a factor of 1.3 or more. An AMG matrix solver option cuts solution time for large models when running a Midplane, Fusion Warp, or a 3D Flow analysis.
