• FEA now supports ALE(Arbitrary Lagrangian-Eulerian) technique using FSI(Fluid-Structure Interaction) analysis
• Stiffness (per unit span) considering the stiffness and mass matrix can also consider both modal and
structural damping.
Upgrade Contents
•Predict fluid and structural interaction behavior.
•Compute fluttering coefficients by performing buffeting and fluttering analysis.

(6) Add Options in Automesh Solid Function
If the geometry shape is feasible for
mapped mesh, try to execute it.
After automeshing, execute
remeshing to attain high mesh
quality.
Even if some parts fail to mesh,
try to execute mesh for all parts.
•Remesh and Map mesh options integrated into auto-mesh function.
Upgrade Contents
•These options can reduce the number of elements generated, increase analysis speeds by generating
higher mesh quality and improve overall accuracy of results.
