It includes the ability to display raw output from thermal models (such as Temperature, Heat Load, etc.) as well as derived data form the same output files (such as Sink Temperatures and Heat Flows). This data is displayed as a transient plot along with the corresponding tabular data. Furthermore, COVeR includes the capability to display heat flows between groups in a block diagram form, which provides a much more intuitive display of the thermal design. Numerous options exist to control the display output, such as heat imbalances, conductance values, color bars, etc. Layouts may be saved and retrieved for use with updated output files or even other cases. These images can be pasted into other programs to help the thermal engineer convey the overall heat flow of the entire model or subsystem of interest.

Thermal Desktop is a graphical user interface for SINDA/FLUINT.
CAD Transfer
Speaker: Joe Lepore, Joe Clay, SpaceDesign
Summary: The Transfer application is used to view CAD models and transfer them into TSS geometry format. Transfer has a ‘CAD viewer’ built-in, allowing you to view any CAD model saved in IGES, STEP, or OBJ format. This viewer shows a meshed representation of the model which can then be transferred to TSS Geometry format in a single step. Using advanced 2-D and 3-D Boolean capabilities (computational geometry), complex CAD entities are converted into thermal surfaces using fewer surfaces for radiation analysis. Transfer methods available include direct conversion to files compatible with TSS v14.01, v13.01 or v12.01, plus a 2-D mesh approximation using surfaces or boundary representation. This class will present a detailed walk-through of the Transfer process, including discussion of B-splines, sequence numbers, composite closed loops, and troubleshooting.
