TriAero is the Triangulated Aerodynamics Suite; a collection of Open
Source Free Software programs intended to perform simplified
aerodynamics calculations over unstructured 3D bodies. TriAero uses the
GTS library
to work with triangulated surfaces.
The source code is available free of
charge
under the Free
Software GPL
license.
The project itself is divided into 4 sub-parts as described below:
1. TriSurf:
TriSurf stands for Triangulated Surface generator. Given an
arbitrary wire-frame geometry supplied through a low level CAD tool,
TriSurf uses GTS to perform successive boolean operations over pairs of
individual
components to generate an water-tight solid model of the input
geometry. The generated geometries allow easy numerical processing for
various aerodynamic analyses.
2. TriWave:
TriWave is an unstructured wave drag code. It is a
replacement for a well known wave drag tool called AWAVE.
Harris Wave drag Code or AWAVE is a tool distributed by NASA Langley to calculate
Zero-lift wave drag of arbitrary configurations. A simple explanation
manual and a sample input and output file can alsobe obtained
from the Virginia Tech website.
TriWave uses the same linearized physics as used in AWAVE,
but the geometry capability is improved using GTS.
3. TriFrict:
TriFrict is an unstructured skin friction tool. The wetted areas of
different components are provided as input. Based on reference lengths,
skin friction is calculated from empirical Reynold's number equations.
TriFrict is better than other existing tools because it uses
water-tight geometries thus providing exact wetted areas for skin
friction computation.
4. TriSHABP:
TriSHABP is an unstructured input file creation tool for running
S/HABP, a supersonic/hypersonic impact code implementing various
leeward and windward analysis options.
Most of the features of GTS are used in the creation of the
source code.
