Creotech Instruments Creates Next-Generation Microsatellites with Multiphysics Simulation
Creotech implements leading-edge methodologies developed by the European Space Agency to design, assemble and integrate critical equipment that meets space standards.
Repairing orbiting microsatellites is impossible due to extreme logistical challenges. Satellite engineers must ensure that equipment is space-proven and extremely reliable before launch. Creating individual satellite components generates high costs, requiring satellite integrators to meet stringent design requirements and satisfy high production process standards. Creotech Instruments’ use of multiphysics simulation effectively addresses these complex challenges.

What's New
The 2025 R2 release delivers transformative advancements aimed at streamlining user workflows, expediting product development, and elevating meshing precision and capability. Ansys Icepak, integrated within Ansys Electronics Desktop (AEDT), now delivers dramatically faster design performance and significantly enhanced mesh accuracy for complex geometries.
TZR Import
TZR imports are now significantly faster and more efficient, delivering up to 1,000 times the speed improvements over the previous release. This leap in performance is driven by the shift from scripted to compiled import, streamlining model transitions and significantly enhancing the overall user experience.
GPU Solver Support
Unlock faster simulation speeds, empowering more design iterations in less time. The advanced GPU solver accelerates a broader range of electronics cooling applications. Expanded capabilities now include robust support for turbulence models, internal fans, Joule heating, transient analysis, non-uniform boundary conditions, sequential solutions, and more, enabling more profound insights and faster innovation.
Thermal Mesh Fusion
Achieve superior mesh quality with enhanced refinement control through incremental levels. Users can now apply positive or negative increments to adjust mesh density, refining or coarsening individual objects as needed. This advancement empowers analysts to create high-quality initial meshes and enables designers to leverage robust automated meshing, driving greater accuracy, flexibility, and efficiency in simulation workflows.
Predict airflow, temperature and heat transfer for electronics assemblies and printed circuit boards
With CAD-centric (mechanical and electrical CAD) and multiphysics user interfaces, Icepak facilitates the solving of today’s most challenging thermal management problems in electronics products and assemblies. Icepak uses sophisticated CAD healing, simplification and metal fraction algorithms that reduce simulation times, while providing highly accurate solutions that have been validated against real-world products.

Thermal Analysis Product Pairings
Improve wireless communications, boost signal coverage and maintain connectivity for antenna systems, predict product performance and establish safe operating temperatures with these product pairings.
| Electromagnetic Losses with Thermal Coupling For Temperature-Dependent Antenna Performance Assessment (Icepak & HFSS) |
|---|
| Ensuring the thermal stability of antenna-enabled 5G infrastructure, automotive radar, IoT devices and mobile electronic devices is critical in producing expected behavior. Power hungry activity such as video calls, online-based games or varying environmental conditions causes significant swings in device temperatures. If a phone’s battery becomes too hot, it can lose charge or even create safety issues. Also, high temperatures can affect other electronic components within a phone and impact RF antenna performance. Breakdown of a phone’s connectivity with mobile carriers, Bluetooth or Wi-Fi is traceable to thermal problems. You can predict these issues before you build the hardware by simulating your design using Ansys tools. For example, electrical engineers can dynamically link Ansys HFSS and Ansys Icepak in the Electronics Desktop to simulate the temperature of the antenna. Based on the electromagnetic and thermal coupling solutions, they can modify antenna design and predict antenna efficiency and the overall thermal and EM performance of the product. These EM and thermal simulations help to improve wireless communications, boost signal coverage and maintain connectivity for antenna-enabled systems. |
| Board-Level Electrothermal Coupling (Icepak and SIwave) |
| Even a marginal rise in temperature can affect the performance and reliability of electronic components, leading to system-wide problems. Board-level power integrity simulations within SIwave can be combined with Icepak thermal simulations to get a complete picture of a PCB’s electrothermal performance. SIwave and Icepak automatically exchange DC power and temperature data to calculate Joule heating losses within PCBs and packages to obtain highly accurate temperature field and resistive loss distributions. These DC electrothermal solutions let you manage the heat produced by your designs and predict thermal performance and safe operating temperatures of chips, packages and boards. |
