The solution time for simulation studies with connectors that support distributed
coupling has been improved.
Expected solver enhancements include:
- Intel Direct Sparse solver. Models that previously failed to solve because of
limitations on the number of coupling facets (surface elements) exceeding 800
can reach a solution. This restriction is removed. In addition, solution time
for models using connectors with distributed coupling and a large number of
coupling nodes (for example, bolt, bearing, and linkage rod connectors) is
faster.
For example, the image above shows a model of two
cylinders that are attached with a bolt with distributed coupling. In
earlier releases, the linear static study of this model failed because of
the limitation on the number of coupling facets. In this release, the Intel
Direct Sparse solver successfully provides a solution for the same
study.
- FFEPlus solver. Faster solution time for models using connectors with
distributed coupling and a large number of coupling nodes.
