Highlights

Altair OptiStruct is an industry proven, modern structural analysis solver for linear and non-linear mechanical problems under static, dynamic, and thermal loads. It is the market-leading solution for structural design and optimization. Based on finite-element and multi-body dynamics technology, and through advanced analysis and optimization algorithms, OptiStruct helps designers and engineers rapidly develop innovative, lightweight and structurally efficient designs. OptiStruct is used by thousands of companies worldwide to analyze and optimize structures and mechanical systems for strength, durability, noise and vibrations, heat transfer, as well as impact.

OptiStruct 14.0.231 release contains the following Resolved Issues.
 

Resolved Issues

•For some Large Displacement Nonlinear Analysis runs, the scratch files generated during iterations were not properly deleted, leading to large disk space usage. This may lead to the run erroring out due to insufficient disk space. This has now been fixed.
•Nonlinear runs with coordinate systems defined on the dependent grids of RBE2 or RBE3 elements may lead to slower convergence. This has now been fixed.
•The shear moduli defined on MAT9ORT were incorrectly assigned to the corresponding MAT9 field during internal conversion. This has now been fixed.
