Thermal Desktop Description
Thermal Desktop encompasses every facet of creating models, integrating various built-in objects like finite difference, finite element, and lumped capacitance that can be arranged in numerous ways. Users can incorporate thermal-specific components such as contact conductance, insulation, heat loads, and heaters, enabling the modeling of a wide range of systems from automotive parts to crewed spacecraft. The software features comprehensive parameterization, allowing input through variables and complex expressions instead of fixed numerical values. These variables, known as symbols, facilitate swift adjustments to models with minimal effort, simplifying the process of updating or maintaining them, as well as conducting sensitivity analyses and exploring hypothetical scenarios. Furthermore, this capability enhances access to SINDA/FLUINTโs modules for optimization and reliability, along with automated model correlation, ultimately enriching the modeling experience. By streamlining these processes, Thermal Desktop not only improves efficiency but also fosters innovation in thermal analysis.

Doesn't compete well with Siemens Simcenter Thermal Edited: Nov 26 2023
Summary: Totally frustrated with Thermal Desktop. And am upset at our incompetent thermal lead for selecting this software as there was nothing wrong with NX Thermal to begin with. Seems like 1-D and 2-D shell meshes are ideal for Thermal Desktop.
Positive: Nothing positive as everything is negative compared to what I used before.
Negative: Sorry, but Siemens Simcenter Thermal is by far a superior thermal analysis software. One can hope ANSYS can improve the thermal desktop products within Mechanical Desktop, but I highly doubt it. At our company we were forced to use Thermal Desktop after using NX Thermal for a couple years. Everything in NX is streamlined. You defeature in NX, go to the pre/post where you enter into NX Thermal, create an idealized part(basically a copy of te CAD), and you suppres curves/edges to mesh and then apply material properties, create advection network for the fem file. Also if there are mesh issues you can manually create elements if need be. Then you progress to the sim file where you apply contacts, bc's, map CFD results and setup the model to run.

In Thermal Desktop we are forced to use ANSYS Spaceclaim to defeature and then link to Thermal Desktop to mesh through a "blackbox" where you can only control the mesh by apply mesh sizing. A total nightmare if the meshing fails.
Also the graphics rendering is absolutely horrible for complex 3-D meshes. Using the space ball to rotate and translate mesh is excruciatingly slow. Opened up a fairly large mesh and just turning on/off layers took a couple hours.
