STRESSCHECK V9 RELEASE NOTES

StressCheck 9.0 Features & Enhancements

This release includes superior user interface stability and graphics performance, larger and faster model solution performance, and improved reliability in saving and retrieving models and databases from current and previous releases.

New Features:

1. 64-bit solver - Use of a batch process running in 64-bit Windows to solve large system of equations (successfully solved 60M equations in 64-bit Windows with 8GB RAM).


2. Pre-load buckling analysis - Allow for the computation of eigenvalue buckling for one set of loads while keeping other set constant. For example, computing the buckling load factor for a set of mechanical loads while accounting for the influence of residual stresses created by thermal loads.

3. Translation utility to convert PATRAN CSV load data into StressCheck format.

4. Selection of multiple files during solid model importation.

5. Provide for the extraction of the stress intensity factor K2 from the Results/Points interface.


Enhancements:

1. Improvements of the 32 bit solver performance and handling of out-of-memory conditions. For example, for problem sizes between 1 and 4 million DOF a fivefold performance improvement relative to V8.

2. Session log reorganization and reformatting to better communicate information to users.

3. Improved handling of error messages.

4. Overall code stability and control of memory leaks.

5. Improvements in the database management.

6. Enhancements to laminate stack records and handling of legacy models (pre-V8).

7. TLAP-Traction and TLAP-Bearing (data management and visualization) to support large number of imported free-body loads. Addition of summation row to the data table.

8. Importation of NASTRAN models (BDF, NAS and DAT files). Automatic element/element/force renumbering to allow multiple importations in the same session.


Discontinued Support for Features:

AOM toolbars are no longer supported in this release. This does not affect the ability to access the features of the user interface by other means. Windows software rendering is replaced with the more efficient OpenGL rendering.
