Maestro 11.2 RELEASED!

January 2016

We are pleased to announce the official release of the new version of MAESTRO.  Version 11.2 features the release of the new module, ProColl Hull, as well as other new and enhanced features.  ProColl Hull is used to determine the progressive collapse behavior of lightweight aluminum ship structures and conventional steel vessels.  ProColl is a tool developed by Professor Bob Dow and Dr. Simon Benson from the University of Newcastle under sponsorship by Dr. Paul E. Hess III, Office of Naval Research (ONR), USA.  Its capabilities have been interfaced with MAESTRO’s existing user interface and post-processing capabilities, and packaged as the ProColl Hull Module.

Please see the details at the end of this email for more information on renewing expired maintenance and support, purchasing the ProColl Hull module, or purchasing a new license.  Current users who are eligible to use this release will receive a follow-up email with the download link for Version 11.2

New and Enhanced Modules

  • ProColl Hull Module: ProColl Hull provides the ability to calculate compartment level progressive collapse behavior of lightweight aluminum ship structures and conventional steel vessels.  This analysis method extends the interframe progressive collapse method by including overall gross panel buckling effects in the determination of hull girder strength.  The background and theoretical basis of ProColl is documented in the MAESTRO Help File.

New and Enhanced Features
The following is a list of the new and enhanced features found in MAESTRO v11.2.  A copy of this list of features can be found in the Release Notes.

  • User-Defined Longitudinal Hull Girder Stations: The user is now able to define non-uniformly spaced longitudinal stations to recover hull girder properties from.
  • Large Model Handling: Several new features have been added to handle large models and analysis including parallel processing to read models faster and run fatigue calculations, and options to speed up group selection and creation.
  • Nastran Export: Property names in a MAESTRO model can now be read into FEMAP.
  • General Group CG Reported: The center of gravity of a general group is now reported along with the self-weight.
  • Delete/Hide Element Dialogs:  Evaluation patches have been added to the selection options for the Delete and Hide Elements dialogs.
  • Stiffener Layout Properties: The stiffener layout create/modify/view functionality is now part of the plate, beam, rod, and spring properties dialog allowing sorting of stiffener layouts.
