  • A Review on Machining of Micro-Structured Optical Molds


    The manufacturing of optics is an important field of technology and will serve keymarkets today and in the future. Nevertheless, the application of complex optical elements is much restricted today despite of their outstanding functional advantages. Furthermore, the replication of structured optical components requires high precision molds.

  • Grid Systems | CFD-101 | What Are the Advantages and ...


    Gridding is the process of subdividing a region to be modeled into a set of small control volumes. Associated with each control volume are one or more values of the dependent flow variables (e.g., velocity, pressure, temperature, etc.) Usually these represent some type of locally averaged values.
