In SOLIDWORKS Simulation Professional and SOLIDWORKS Simulation Premium,
for static studies only, the Underconstrained
Bodies algorithm includes contact interactions and bolt connectors when
detecting rigid (or free) body modes of components.
In SOLIDWORKS Simulation Standard and
SOLIDWORKS Premium, the Underconstrained Bodies
algorithm does not include these improvements and remains unchanged from previous
releases.
To open the Underconstrained
Bodies PropertyManager:
In the Simulation study tree, right-click
the Connections node, and click Find Underconstrained Bodies.
The improved algorithm offers the
following advantages compared to the legacy
Underconstrained
Bodies functionality:
- Faster detection of free body modes because the solver performs
Singular Value Decomposition (SVD) over the reduced stiffness matrix.
- Inclusion of contact interactions and bolt connectors when
analyzing free body modes.
- Realistic visualization of free body modes in planes that are inclined to
the orthogonal planes that are defined by the global X-, Y-, and Z-axes.
- Improved visualization of unconstrained displacements for the
whole assembly.
