Automated Thermal Analysis with CAD AssociativityCRTech Thermal Workshop™ provides the Thermal Desktop® user with the ability to add thermal model information to a CAD drawing, and to extract and mesh complex parts and assemblies. It accelerates thermal engineering tasks by providing new predictions automatically when the design changes. Thermal Workshop also provides a path toward multidisciplinary analyses and system engineering activities. Thermal Workshop will be released in early 2011 coinciding with the release of Thermal Desktop version 5.4. For more information about Thermal Desktop or to schedule a demo, please contact C&R Technologies, Inc.

Thermal Workshop provides capabilities for importing native CAD (e.g., Pro/E, Solidworks, NX CAD), and ACIS files, and passing corresponding meshes and other model information seamlessly into Thermal Desktop. In the Thermal Workshop environment, objects may be “tagged” as needed to describe boundary conditions, contact conductance, heater locations, etc. Once the analysis process has been created and saved, if the CAD geometry is altered, then the process can be used to automatically update the Thermal Desktop model. The Thermal Workshop environment provides access to other multidisciplinary and multi-physics engineering analysis. Thermal Workshop is CRTech’s exclusive thermal-specific version of Comet™, the innovative multi-physics engineering analysis environment from Comet Solutions, Inc. Developed specifically to integrate with Thermal Desktop, Thermal Workshop greatly extends the capabilities of the Thermal Desktop user. Thermal Desktop users will find the Thermal Workshop interface to be very familiar and intuitive. Material and optical properties, boundary conditions, tags, and concepts specific to RadCAD such as radiation analysis groups are applied to the CAD geometry and carried through to the resulting mesh that is sent to Thermal Desktop. Detailed mesh controls are available to create a custom, thermally-appropriate mesh. These customizations are also preserved if the design geometry changes.
Additional Information
Introduction
Thermal Workshop is a tool that integrates and automates the preparatory tasks performed by the thermal engineer. Specifically, it contains capabilities for importing a CAD model, creating an analysis model from the design geometry, launching Thermal Desktop and SINDA/FLUINT thermal analyses, and seamlessly mapping results to a structural model. It integrates and manages the execution and data flow between the various tools used to perform the CAD import, meshing, analysis, and data export tasks. Thermal Workshop does not replace Thermal Desktop. Rather, it augments and significantly extends the analysis capabilities. It provides innovative new functionality that is applicable to all aspects of thermal engineering for all phases of the product life cycle. It provides powerful analysis capabilities as well as systems engineering features to track compliance with requirements. Thermal Workshop Process Thermal Workshop and its companion modules are more than just a suite of powerful tools. The thermal process can be re-executed to accommodate changes in design with a simple right-click of the mouse and selecting “run” from the context menu. Through the use of the Process Schematic and Abstract Modeling, Thermal Workshop creates full associativity between the CAD model and the resulting thermal model entities.
Typical Process Schematic Engineering processes are captured using a Process Schematic, which graphically depicts analysis tasks and the data that flows between those tasks. Users create new process schematics interactively, or they may simply use previous processes that have been captured and saved as a template.
Example of a Motor Imported to Thermal Workshop, Meshed, and Exported to Thermal Desktop Abstract Domains
Surfaces Tagged for Automatic Thermal Connections Such as Contact Conductance Key extensions to Thermal Desktop have been implemented to exploit the use of abstract domains. Virtually every Thermal Desktop thermal entity, such as a heat load, a node-to-surface conductor, the boundary condition mapper, or a contactor can accept an abstract domain or “tag” for the thermal entities on which they operate. Thermal model data that is created by Thermal Workshop and then imported into Thermal Desktop contains these tags, which were applied to the original CAD geometry. For example, if the FE solid representing part of the aforementioned wing structure is more coarsely meshed, or even replaced by an FD solid, it doesn’t matter since the “leading_edge” tag will still apply. Propagation of Design Changes When the CAD geometry is changed and the engineer wishes to update the thermal model and generate new results, the process schematic is simply re-executed. This causes the CAD geometry to be re-meshed, then this new mesh is automatically imported into Thermal Desktop, and any loads, boundary conditions, and connections are automatically and seamlessly re-applied.
Design Updates Seamlessly Incorporated into an Existing Thermal Model The use of abstract domains and an automated process schematic allows updates to be seamlessly incorporated into an existing thermal model. The analyst can decide which portions of the thermal model are best built and managed in Thermal Desktop, and which portions should be associated with CAD model and originate within Thermal Workshop.
