The introduction of
a
distributed coupling algorithm enhances the performance of studies
that use pin connectors.
Results from studies with pin connectors that
you apply to cylindrical surfaces with large number of nodes and use the Distributed connection are more accurate.
The solution time for these studies is
improved for the Intel Direct Sparse solver.
In previous releases, when the number of nodes
were very large, only a subset of the nodes participated in the distributed coupling
constraints. In SOLIDWORKS Simulation 2025, the distributed coupling constraints for pin
connectors include all the nodes on the cylindrical surfaces.
The
solution time with the FFEPlus iterative solver for similar studies is unchanged in
SOLIDWORKS Simulation 2025. However, the stress results are more accurate because
all nodes are considered in the distributed coupling formulation.
This enhancement is available for Linear Static
studies, along with the associated Fatigue, Design, and Pressure Vessel Design
studies.
