Key features
D-LFT fiber orientation
D-LFT strands are manufactured in an extrusion process, which induces a local fiber orientation. Use our approaches to initialize the local fiber orientation in D-LFT strands, as the basis for accurate prediction of the fiber orientation in the final part.
Data transfer
SimuFill enables the data transfer between Abaqus and Moldflow. This enables modeling material forming and material flow in Abaqus and Moldflow, respectively. Based on this, the best-suited numerical technique is used for each stage.
pvT modeling
Accurate modeling of the pvT behavior is crucial for the accurate prediction of residual strains due to thermal elongation and shrinkage. Residual strains in turn induce residual stresses and warpage. SimuFill provides sophisticated models for predicting the pvT behavior as a function of the degree of conversion for both, thermoplastics and thermosets.
Crystallization kinetics
Accurate prediction of crystallization kinetics ensures accurate prediction of mold filling and part warpage/spring-in. SimuFill provides the Nakamura-Ziabicki model for Moldflow, which is also used by SimuWarp, our add-on for warpage analyses in Abaqus.
Curing kinetics
Accurate prediction of curing kinetics ensures accurate prediction of mold filling and part warpage/spring-in. SimuFill provides different curing kinetics models for Moldflow, which are used by SimuWarp, our add-on for warpage analyses in Abaqus.
