Durability is the study of how long a part will last and fatigue is the mechanism of damage that causes durability failures. Cycling loads are the most important contributor to fatigue failure, but material properties are just as important, and hand calculations can lead to mistakes or incorrect judgement. As a software solution, fe-safe has been used for years along with FEA solutions such as Abaqus, Ansys, Nastran and others. Along with other optimization and product integration software,

Hello everyone, I'm having trouble simulating a Vivaldi antenna. My S11 is stuck near 0 dB when I use a coaxial feed, but the simulation works when I use a simple discrete port. My Setup: The main antenna body is Aluminum. I have an FR-4 substrate on top with a Copper microstrip line for the feed. I am using a waveguide port to model the coaxial connector. The most interesting behavior is that if I simplify the model to only the bare aluminum radiator and excite it with a discrete port

Hi, We have simulated a ceramic BLE antenna in two scenarios: with and without wood nearby. In the simulation, we observed that the presence of wood causes a shift in the S-parameter and reduces the antenna efficiency by about 30%. Without wood, the efficiency is around 70%. However, in our real lab tests, the S-parameter only shifts when the PCB is in direct contact with the wood. If there is any separation, the effect is minimal or nonexistent. Is it normal to see such a discrepancy between
