RadCad

de C&R Technologies

RadCAD es un analizador de radiación térmica disponible para su uso con Thermal Desktop o como programa independiente. RadCAD usa algoritmos Monte Carlo para el cálculo de factores de forma, conductores de radiación y tasas de calentamiento para representaciones de superficies cónicas.

RadCAD is a thermal radiation analyzer available for use with Thermal Desktop or stand alone. RadCAD uses Monte Carlo Ray Tracing to calculate form factors, radiation conductors, and heating rates for true conic surface representations for input into SINDA/FLUINT. RadCAD is the first radiation analyzer to integrate arbitrary CAD generated surfaces with familiar parameter-based (TRASYS like) surfaces.

Why use RadCAD
There are many reasons to use Thermal Desktop/RadCAD and a full report can be found here. A quick summary of the three major reasons is listed below.

  • Thermal Desktop/RadCAD uses snap on model building. Thermal Desktop is CAD based. This allows Thermal Desktop to take full advantage of CAD model building. Whether you are sketching your Thermal Desktop surfaces over an IGES wireframe or snapping new surfaces to the referenced points of existing surfaces, you'll find that you are building your model more accurately and faster than ever.
     
  • Thermal Desktop/RadCAD runs on a PC. Finally, the thermal engineer doesn't need two computers. Thermal Desktop runs on the same PC under the same OS as your word processing system (see system requirements for details). No more transferring your phone and going to a computer room. You can work right at your desk and easily switch between developing your model and documenting it.
     
  • RadCAD is fast. RadCAD uses proprietary advances in Monte Carlo ray tracing to achieve remarkable calculation speed. One significant advance is the progressive radiosity routine used to turn view factors into radiation conductors. At C&R, we are keeping up with the latest technology to provide users with the fastest most accurate solution possible.
