Summary
The problem to be simulated is the inviscid, subsonic flow of air past a cylinder. The diameter of the cylinder is 1 m. The flow has a free-stream Mach number,M∞ , of 0.177. The numerical model employs only a semicylinder due to the symmetry of the flow pattern around the cylinder.
Details

This tutorial covers the following subjects:

  • Setting a model name and title for the problem
  • Reading a single domain, DTF grid, and building a CFD-FASTRAN model
  • Setting fluid properties such as molecular weight
  • Setting initial values for the flow field
  • Setting boundary conditions appropriate for theinviscid flow problem
  • Setting solution iterations and cycles
  • Choosing a suitable time-integration scheme and setting CFL numbers.
