Shadow Tracking

Using RadCAD® for Shadow Tracking

Using the Monte Carlo ray tracing capabilities in RadCAD, Olivier Godard and Tejas Shah came up with this visual simulation of tracking the shadow of the International Space Station (ISS) on the belly of the Space Shuttle. The Shuttle is oriented with the payload bay doors looking nadir (facing earth) while the ISS, traveling at the same speed at a slightly higher altitude, passes over the belly of the shuttle blocking the sun's light.

The image has been postprocessed in RadCAD with the scale on the left representing the nodal heat flux, the view being the shuttle belly. The color scale maximum is 1354 W/m2 which represents full solar heating. As the ISS passes over the shuttle, the resulting shadow or blockage is displayed by the blue color (0 W/m2).

This simulation could have been performed using a raytracer for animated movie rendering but the advantage of RadCAD is that you can obtain a similar result directly applicable for other thermal related computations.

This example of using RadCAD to track IR and solar shadowing has been provided by Igor Carron of the Spacecraft Technology Center at Texas A&M University.

FloCAD online training

Class times: May 2 & 4 from 10am to 2pm MT

Cost: $425

This online class will provide an introduction to fluid modeling components within FloCAD. The class will be held over a 2-day period, with daily sessions running approximately 4 hours each. The class uses a mixture of lecture, demonstrations, and self-paced tutorials to allow attendees to practice building fluid system models and interpreting results. The presentations will comprise 2 - 3 hours of each session, and the instructor will be available during the remainder of the time for questions during tutorials. Attendees must have basic working knowledge of SINDA and Thermal Desktop as these topics will not be covered but their usage is required for FloCAD.

Using Sinaps? It is not too soon to get started with TD/FloCAD!

This webinar describes the process for converting from Sinaps to Thermal Desktop (TD) and FloCAD. This process includes using an exporter which works with Version 6.0 of the CRTech tool suite (expected to be released in May of 2017).

Come learn about the basics of TD/FloCAD, including many compelling features not available in Sinaps. The webinar will also cover how to manage the transition period, during which you may be using both programs simultaneously. This is also a chance to ask questions.
