Summary of main themes

  1. Despite great advances in computer-aided engineering, certain deficiencies remain, of which the chief are:
  2. Some progress can be reported regarding the CAD-to-CFD difficulty, with the STL format proving to be of key importance.
  3. It will be shown that solid stress and fluid flow can be analysed by a single algorithm, a single code, and therefore a single specialist.
  4. In respect of turbulence and radiation, the LVEL and IMMERSOL models are advocated as being good compromises between economy and realism for simple circumstances; and MFM, the "multi-fluid model", promises the same for more complex ones.
  5. Remote computing-plus-advisory services reduce the expense of computer-aided engineering.
