![]() ![]() However, as I more recently evaluated CFD software and its integration graphical interfaces, I came to realize its power not only in flow, but also in thermal analysis, which was my main area of interest at the time. Initially, I did not see many practical industrial applications for CFD and stuck with custom code, rules of thumb and spreadsheets to get the job done. 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.I had been a finite element user for many years before entering the world of flow simulation/computational fluid dynamics (CFD). 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. 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. These EM and thermal simulations help to improve wireless communications, boost signal coverage and maintain connectivity for antenna-enabled systems.īoard-Level Electrothermal Coupling (Icepak and SIwave)Įven a marginal rise in temperature can affect the performance and reliability of electronic components, leading to system-wide problems. 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. For example, electrical engineers can dynamically link Ansys HFSS and Ansys Icepak in the Electronics Desktop to simulate the temperature of the antenna. You can predict these issues before you build the hardware by simulating your design using Ansys tools. Breakdown of a phone’s connectivity with mobile carriers, Bluetooth or Wi-Fi is traceable to thermal problems. Also, high temperatures can affect other electronic components within a phone and impact RF antenna performance. ![]() If a phone’s battery becomes too hot, it can lose charge or even create safety issues. Power hungry activity such as video calls, online-based games or varying environmental conditions causes significant swings in device temperatures. Electromagnetic Losses with Thermal Coupling For Temperature-Dependent Antenna Performance Assessment (Icepak & HFSS)Įnsuring the thermal stability of antenna-enabled 5G infrastructure, automotive radar, IoT devices and mobile electronic devices is critical in producing expected behavior. ![]()
