Thermal Simulation

ANSYS, Network Analysis announced a combined product that integrates the SINDA/G thermal analyzer into the ANSYS Workbench modeling system.

The SINDA/G for ANSYS Workbench plug-in is a transparent integration of SINDA/G into ANSYS Workbench. Of benefit to both beginning thermal modelers and advanced thermal analysts, the transparent integration allows users to utilize advanced thermal features involving convection, surface-to-surface radiation and orbital heating without needing to know the format of SINDA/G or thermal radiation codes. Experienced SINDA/G users no longer will be limited by the simple boundary conditions typically associated with finite element analysis (FEA) thermal codes: They now can experience the full power of SINDA/G within the ANSYS Workbench environment.

"ANSYS Workbench is one of the most user-friendly and easy-to-use simulation environments that has ever been created," said Ron Behee, president, Network Analysis, Inc. "Through the cooperation of our two companies, ANSYS users now have access to advanced thermal features found in SINDA/G, and SINDA/G users have a powerful and user-friendly simulation environment."


"Collaborating with Network Analysis provides ANSYS Workbench users access to the many unique features of the SINDA/G thermal solver. The interface also provides access to major thermal radiation codes to allow orbital heating effects to be included in their satellite simulations," said Joe Solecki, vice president, mechanical business unit at ANSYS, Inc. "Now satellite models generated in ANSYS Workbench can be solved for transient temperatures during orbit. These temperatures can be used in subsequent thermal/stress predictions. This is one additional step in providing our customers with a complete simulation solution."

The mechanical analysis products from ANSYS, Inc. incorporate a graphical modeling environment ideal for producing SINDA/G thermal models. These models have enhanced the concurrent engineering processes by allowing temperatures computed from advanced SINDA/G models to be used by simulation software from ANSYS for thermal stress/distortion computations. Since many thermal engineers already are familiar with the ANSYS Workbench environment, the learning curve for the SINDA/G plug-in is greatly reduced, thus eliminating the need to learn another modeling system.

The SINDA/G plug-in has powerful connections to thermal radiation codes such as THERMICA, NEVADA, TRASYS, TSS and NAI's fast new radiation solver SINDARad. Spacecraft thermal models now can be created in the ANSYS Workbench environment, and the orbital thermal environment can be defined by utilizing one of these thermal radiation and orbital heating codes.

SINDA/G is a trusted thermal design system. When integrated into an FEA modeler such as the ANSYS Workbench platform, these finite element models are translated into a SINDA/G network thermal model. SINDA/G is stable and can quickly solve large complex nonlinear thermal models involving temperature-dependent thermal properties, radiation and orthotropic material properties.
