Background information

  • Quarry vm on image info
  • from Michael Banks
    I am currently building a web application that allows users to simulate the fluid flow past a cylinder via a connection to the San Diego Supercomputer Center. 
    The user needs to be able to choose from a list of parameters before they run the simulation.
    The output will be a single .mpg no more than 35Mb in size and plots for lift and drag.
    The video will not be saved for more than a few days.
  • application name is "vortexshedding"
  • now on jetstream.
