  1. Hi, May i ask what is meant by volume fraction in topology optimisation? Have read a few responses but dont quite understand still. Why does it seem to be standard to use 30% vol frac? Also, is there a minimum acceptable volume fraction? Thanks!!
  2. Hi, I would like to carry out topology optimization on the wing rib that takes the shape of the airfoil to obtain results like the one depicted in the attached image (obtained from http://web.aeromech.usyd.edu.au/WCSMO2015/papers/1218_paper.pdf). However, i am not sure how to define the varying pressure magnitude (and other loads) acting on the airfoil along the chord length. Is there anyway to import a data file detailing the magnitude at specific positions of airfoil? Thanks.
  3. Hi, Does anyone have any tips on how to go about optimising the internal structure of an aircraft wing? I am a very new user to Hypermesh. Thanks.
  4. Hi Toan, I have attached the file. The first column indicates the chord wise position around airfoil from the leading edge in the clockwise sense, and the second column indicates the magnitude of pressure i wish to apply on the airfoil. Thanks so much for your help. Amanda Cp.dat
  5. the graph data is in dat. format
  6. Hi, I am new to Hypermesh and am trying to analyse the load that will be exerted on the airfoil based on the pressure distribution along the airfoil (refer to pic). Is it possible to import these values from the graph into hypermesh?
