Summary
Helius PFA for Plastics provides an integrated, simple approach to
link the as-manufactured plastics simulation properties with
structural simulation to increase FEA accuracy Insight Ultimate 2018 Subscription customers have access to Helius PFA
Dissimilar mesh can be used (mapping suitability check)
Moldflow users can pass results to structural users
Simple interface for integration of both software packages
