Solver Enhancements for 2021.2

Enhancements have been implemented to improve the performance of analysis solvers, and to provide you with better solutions.

Improved Warpage Calculation Accuracy for 3D Cases

The residual stress calculation for 3D cases have been changed. For some cases, the accuracy of 3D Warp predictions is improved significantly. Further, the accuracy of some 3D Warp analyses without manual constraints depends on the automatic selection of constraint nodes to fix the rigid body motion. In the new release, the automatic constraint selection has been improved. This change may bring minor result changes in all 3D Warp cases.

Removed Memory Limitation for 3D Warp

In the past, there was a limitation on the maximum mesh size which can be run by 3D Warp due to limitations in the memory management scheme. This mesh size limitation restricted the complexity of models which could be run by 3D Warp. In the new release, this memory limitation has been removed.
