Good Looking Mesh May Not Always be Good for the Simulation
As a computational geometry developer I have worked on several meshing software development projects. Every time mesh quality has become focal point. As matter of fact this becomes conflicting topic between the various teams due to the difference of opinion in engineering community.

Selection in CAD Using OpenGL Graphics Programming
For any CAD developer who is developing interactive CAD application one of the important topic of interest is Selection or Picking. However this topic is not discussed in detailed in most of the OpenGL resources. I hope this article helps you understand basic techniques available for selection.

Shading Normals using OpenGL - Graphics Programming
The most general form of the lighting equation uses both the vertex position and a vector that is normal to the object’s surface at that position; this is called the normal vector. Ideally, these normal vectors are captured or computed with the original model data, but in practice there are many models that do not include normal vectors.

Model Tessellation and Visualization using C++ API in Autodesk Inventor
Autodesk Inventor provides powerful API interface the access the model tessellation and visualization. This blog series attempt to explain how to use Inventor C++ API to get a triangulated geometry from Autodesk Inventor model for downward processing. Assembly document, part document and sheet bodies are covered as model geometry for tessellation.

Performance evaluation of micro gas turbine with CFD
A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. A turbine is a turbo machine with at least one moving part called a rotor assembly, which has a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor.
