Discription

The new CML GPU Dynamic simulator is different from its predecessor in the following ways:

  • Using GPU technology to gain speed (2.5X acheived in the example case)
  • better memory handeling
  • You need to install compatible NVIDIA GPU. This code has been tested on a GeForce GTX 960

Discription

The new CML Dynamic simulator is different from its predecessor in the following ways:

  • Addiction of an accurate reduced order finite element suspension.
  • We've moved from a three degree of freedom slider model to a six degree of freedom slider model.
  • Users can now enter a 2-D point by point disk topography. Previous versions of the simulator allowed the input of a 1-D point by point disk topography.
  • This version have a bug fix for the minimum spacing calculation.
  • bug has been fixed regarding flyheight output when disk waviness involved.

Description

Determines dynamic flying characteristics of arbitrary rail shapes under user specified run conditions. Simulates take-off, landing, CSS, track-seek, crash stop, and more. Incorporates contact model and disk texture capability.

New features for this release include:

    • Finite element modeling for the suspension
    • Modeling of user defined ramp profiles
    • Simulation of shock and vibration
    • Improved elastic impact modeling
    • Inclusion of intermolecular forces
    • Update (10/7/07): The simulator can now support grid sizes up to 994x994 and up to 200 points in each rail
