ESTECH.PlotTool

Feature

• Display output of MSC Nastran contribution analysis effectively.
• The software is compatible with the following 3 types of commands for the different contribution ratio displays which MSC Nastran provides.
  • MCFRACTION : Mode contribution display for frequency and transient responses.
  • FLSPOUT : Mode contribution display due to pressure response for structural mode, acoustic mode, acoustic load, panel, panel structural mode and gird point mode.
  • PFMODE/PFPANEL/PFGRID : Mode contribution display for structural mode, acoustic mode, panel structural mode and contribution display for panel and grid point.
• Together with ESTECH.NAST+, the following output are able to be displayed, which is not provided by MSC Nastran.
  • Contribution display of velocity and acceleration response
  • Modal acoustic radiation coefficient, which enables engineer to study the optimized allocation of resonant frequencies of structural modes.
• The software identifies modes and panels which have higher contribution to the phenomenon instantly, which makes an interactive operation workable even though the numbers of modes are more than 1000.
• For Adams application, the output of time domain response analysis is disintegrated for contribution of the natural mode contribution, which is displayed. Even the animation in time domain analysis generates small amplitudes and it is not easy to capture its distortion behavior only from time domain wave pattern, the software captures the distortion behavior by combination of natural modes with distinct deformation.
• Especially, the above-mentioned features are advantages to analyze performance of driving over bumps by　a vehicle tire, which is unable to apply Adams because its input is hard to identify.
