GENESIS 10.1 Released


GENESIS 10.1 and its companion Design Studio for GENESIS 10.1 have been released. CD-ROMs will soon be shipped out to current clients. Contact VR&D for instructions on how to download the new version if you don't want to wait for the CD.

New features and enhancements include:

  • Support for the Equivalent Static Load Method.
    This version of GENESIS includes a new feature aimed at supporting the Equivalent Static Load method for optimization with nonlinear analysis. Displacements produced by other codes can be read into the program and the program will automatically calculate equivalent static loads that produce the same displacements. To use this functionality you need to obtain a special reader for the code of interest. Please contact VR&D for more information on how to obtain readers.
  • More efficient modal frequency response calculations.
    GENESIS now avoids unnecessary calculations, resulting in reduced runtime and disk space requirements.
  • Faster solvers.
    All solvers are now faster on Linux systems with Intel Pentium4/Core2/Xeon processors. Up to a 40% speed increase has been observed in some problems.
  • More efficient handling of rigid element and MPC constraints.
  • Updated formulation for RBE3 element.
  • Random response optimization for all types of optimization.
    Root mean square displacement, velocities and acceleration can be used as objective or as constraints.
  • New fabrication constraint for topography optimization.
    This new fabrication constraint (BEADFR) usually results in clearer bead patterns and less variability in the results.
  • Design variable selection.
    A new data entry (DSELECT) asks the optimizer to select the best set of design variables to move to their upper bound and the rest to their lower bound. This new capability allows easy formulation of optimization problems such as selecting the best locations of welds or selecting among candidate designs.
  • Enhanced minimum member size fabrication constraints.
    Topology optimization now accepts minimum member size without the need to specify any other fabrication constraints. Minimum member side can still be mixed with all appropriate existing fabrication constraints.
  • Performance improvements for topology.
    Several opportunities to eliminate I/O were identified in topology optimization. Many problems will run faster due to reduced disk access.
