The following figures show
you how simple it is for FluSol to generate 3D finite element meshes for
arbitrary number of wings and body combination. At the same cross section, user
can specify up to 4 wings. The generated body cross section can be a circle or
an ellipse shape. 3D full or half (symmetry) meshes can be generated by one
command. FluSol will also generate corresponding initial and
boundary conditions at the same time. After the Euler or Navier Stokes
calculations, the pressure force coefficients
(CDX, CDY, CDZ) at any specified surface will be integrated. The whole
process of generating 3D mesh takes less than one hour instead of days. Another
advantage of this tool is that, by using the explicit scheme to solve the fluid
flow equations without matrix operation involved, very large problem can be
handled easily with limited RAM space. A PC with 1 Giga bytes of RAM can be
used to solve the 3D Euler flow problem with CFD model contains 700,000
elements.
