Simulation accuracy is improved for studies with bonded curved surfaces
(surface-to-surface bonding formulation) when the mesh sizes of the source and target
surfaces differ.
The algorithm that enforces surface-to-surface
bonding integrates geometry correction factors that improve the representation of curved
surfaces of cylindrical, spherical, and conical geometries. The integration of surface
geometry correction reduces the stress noise at the vicinity of bonded curved surfaces,
thus improving the solution accuracy.
The image above shows the stress noise
reduction at the boundary where solid-to-solid bonding with geometry correction is
applied between two curved surfaces. The geometry of the bonded surfaces is shown in the
image below.
The studies that support this enhancement
include Linear Static, Frequency, Buckling, Linear Dynamics, Fatigue, Design Scenario,
and Pressure Vessel.
