6DOF Spline Technology
• Technology developed specifically for Structure to Structure (6 DOF) load
mapping and for Aero to Structure coupling.
– Forces and Moments are CONSERVED using spline methodology
– Target FE structure can be any dimension (1D beam model, 2D shell
model or 3D solid model)

HSA Toolkit Overview
• Complete environment to integrate CFD data in Nastran (Static Aeroelasticity
SOL144) and transfer load/displacements between dissimilar meshes
• Plug-in to Patran and Flight Loads
MSC Software Confidential 8
Aeroelasticity Toolkit
• Import 3D aerodynamic mesh and CFD pressure
load as:
– BDF Nastran file
– Tecplot file
– CSV file
• Transform CFD pressure automatically into aero
forces
• Transfer aero forces to structure (Spline6/7) and
solve the structure (SOL144)
• Get and export aerodynamic mesh deformation
