Maestro 10.0 RELEASED!

April 2012

We are pleased to announce that the new version of MAESTRO has been released and is posted on our website.  Version 10.0 features four new modules, as well as incorporating improvements based on suggestions and comments that we’ve received from our customers and beta testers.  The new modules include MAESTRO-Wave, which is an integrated frequency-domain computational tool to predict motions and wave loads, Extreme Load Analysis (ELA), Spectral Fatigue Analysis (SFA), and the MAESTRO/NAPA Interface which allows the designer to import a NAPA/NAPA Steel 3D model into MAESTRO.  These modules are now available for purchase, and we would like to extend a thank you to all who have provided feedback to us throughout the development process.

A link to download the update is given below. Please read through the following information before you download.

New and Enhanced Features
The following is a list of the new and enhanced features found in MAESTRO v10.0.  A copy of this list of features can be found in the Release Notes.

  • MAESTRO-Wave:  New module which provides the ship designer with an integrated frequency-domain computational tool to predict the motions and wave loads of any vessel.  To compute these hydrodynamic motions and loads, MAESTRO-Wave first calculates the velocity potentials, source strengths, and flow velocities at the centroids of the hydrodynamic panels for each speed, heading, and frequency requested, and then maps the source strength to the structural panels. The equations of motion are formulated using the structural mesh rather than the hydrodynamic mesh. This approach results in a perfect equilibrium for the structural model. Bending moments, shear forces, and torsional moments are automatically in closure. No inertia relief and artificial loads are needed to balance the model. The computation of these hydrodynamic forces is based on 3D potential theory using the zero speed Green’s function with a speed correction parameter.  A variety of visualizations and output data are available for purposes of post-processing.
  • Extreme Load Analysis (ELA):  New module which imports unit wave load data from a hydrodynamic analysis (MAESTRO-Wave or other) via *.smn file format. It then allows the user to calculate hull girder load response RAOs, and provides the necessary short-term and long-term statistical computations to predict extreme values of the maximum loads for a given vessel.
  • Spectral Fatigue Analysis (SFA):  New module which provides the ability to perform global fatigue screening of the vessel.  The SFA module introduces additional functionality to the ELA module to compute Stress RAOs, displacement RAOs, define and associate structural groups to SN curves and Stress Concentration Factors (SCFs), and compute fatigue damage based on the Miner cumulative damage principle.
  • NAPA/MAESTRO Interface:  New module which allows the designer to import a NAPA/NAPA Steel 3D model, which includes the finite element model (geometry, scantling properties, and finite elements), loading information (longitudinal weight and bending moment distributions, tank boundary/content/fill definitions, and hydrostatic equilibrium definition), and model hierarchy definitions such as MAESTRO module group.  This interface enables shorter design cycle times by using a single 3D structural design model (from NAPA) that can be re-used as the design matures and is ready for analysis in a matter of minutes.
  • VERES Export:  Allows user to export MAESTRO model information to *.MGF, *.M3D, and *.M2D files to support VERES analyses.
  • PRECAL Export:  Allows user to export MAESTRO model information to *.HUL, *.HIN, and *.CND files to support PRECAL analyses.
  • 64-bit Version:  Now available in a 64-bit version.
  • ALPS/ULSAP Update:  This module has been updated to version 2011.2.
  • Results View Updates:  When user-defined range is set, elements below that range are set to blue and elements above that range are set to red.
  • Expanded Group Organization Feature: Allows subfolders to be created underneath the default group types in the groups tree. 
  • Drag and Drop Group Creation: Groups may now be dragged and dropped from one type to another to automatically extract certain elements from an existing group.  For example, nodal groups can be created from plate or general group and shell elements may be recovered from node groups or a general group.
  • New Tank Features: Allows volume groups to be defined as flooded to model flooded or damaged conditions.  User can adjust tank permeability and apply deballast pressure.
  • Hull Girder Load Target: The hull girder load target is a new load pattern that can be used to ensure that either a minimum shear force envelope or a minimum bending moment envelope is met, or to add an additional shear force or bending moment on top of all other load patterns.
  • Create Boundary Modules: Option to assist in applying end moments.  A master node is automatically created and joined by RBE2 elements to all nodes at modules ends to ensure that plane sections remain plane.  End Moment load is then applied at this master node.
  • Weight and Buoyancy Density Plot: Option to plot weight and buoyancy per unit length for easier comparison to other hydrostatic programs.
  • Create Module from General Group: Right-click menu option to create a new module consisting of the elements defined in the selected general group.  These elements are removed from their original module.
  • Extract Module: Option to create a new module by “extracting” elements from an existing module by defining a bounding box.  This allows large or full ship imported models to be easily separated into more manageable modules.
  • Define General Group from List of Nodes or Elements: Select multiple elements/nodes from the grid tab and create a general group using the right-click menu.
  • Mass Distribution Exclude Nodal Groups: The mass distribution load pattern now allows selected nodal groups to be excluded from receiving the loading.
  • Speed Enhancements: MAESTRO’s loading speed has been increased for models with large numbers of groups defined.  The auto-creation of evaluation patches has also been increased to handle larger and finer meshed models.
  • Displacement Direction Plot Added:  Option to select single direction only (i.e., X, Y, or Z) to plot deformation.  Also added option to plot “true” scale deformation.
  • Cutting Planes added to Right-Click Menu:  The same cutting planes menu that appears in the Tools menu is now added to the menu when you right-click the mouse in the modeling space.

Upcoming Tradeshows
We are planning to attend a select number of conferences during this year and hope to see you there.  Here is a list of upcoming tradeshows we expect to attend:
ICMT 2012 (6/25 – 6/28, Harbin, China)
SNAME 2012 (10/24 – 10/26, Providence, RI, USA)
