11/9/2004
Dynamic Design Analysis Method (DDAM)
- Improved support for maintaining confidentiality of user-specified input coefficients
9/30/2004
Dynamic Design Analysis Method (DDAM)
- Added options to specify the range of frequencies to be included in results
- Improved ability to control modes participating in Navy Research Laboratory (NRL) sum calculations
- Improved accuracy for shock analysis involving spectrums acting in multiple directions
9/18/2003
Linear Dynamic Analysis
- Added a new spring element
11/1/2002
Dynamic Design Analysis Method (DDAM)
- Added ability to only use velocity inputs to define the applied shock waves
- Added optional automatic modal mass inclusion, enabling the inclusion of only results with a modal mass greater than a specified percentage or the automatic sorting of modes in decreasing order of effective modal mass to highlight important modes - especially for large models
Linear Dynamic Analysis
- Improved calculation of resultant stress values such as von Mises and principal stress
9/6/2001
Dynamic Design Analysis Method (DDAM)
- For unit systems other than English (in), any analysis attempt that does not have a user-specified definition file will exit with a message
- When using a user-specified definition file and a unit system other than English (in), all unit indicators are suppressed in the ASCII output
- Improved support for models that are in a unit system other than English (in) through additional feedback and use of the user-specified definition file
5/25/2001
Dynamic Design Analysis Method (DDAM)
- Added calculation and reporting of the effective modal mass and participation factors
- Improved output to provide a summary printout in an industry-standard format
- Expanded support to specify the shock load through spectrums acting in any direction
- Added ability for user-specified input coefficients for the design value formulas to be read from a design value definition file while maintaining confidentiality of input
Linear Dynamic Analysis
- Improved messaging, handling of user-specified options and feedback of error messages in log files
- Improved formulation for calculating resultant forces and stresses for beam elements using the NRL (Naval Research Lab) Method
- Improved support for analyses on models including hidden parts
