"We can import CAD models directly into theANSYS EM simu- lation package. The coupled thermal-electromagnetic tools provide us with insight into interactions between pacemakers and M RI scanners, which is a very complex problem. Using simulation allows us to really understand the problem so that Mariya Lazebnik Senior Scientist Antenna with radome solved using HFSS hybrid finite element-boundary integral solver Differential signal propa- gating in time through a flexed cable, solved with HFSS transient using conformai finite elements HFSS transient is a 3-D full-wave transient, or time domain,...

Electric field at WiFi frequency calculated inside modern jetliner HPC options leverage compute power to rapidly solve large-scale EM field simulations with rigor and accuracy. Domain Decomposition The domain decomposition method (DDM) accesses the memory of a network of machines to simulate very large models. HFSS determines the optimal number of subdomains based on mesh size along with the number of processors/ machines available; DDM automatically splits the finite element mesh into a number of subdomains. Each subdomain is analyzed separately, then an iterative procedure on the subdomain...

The ANSYS distributed solve capability allows a single user to distribute parametric studies or frequency sweeps across a number of computers, expediting total simulation time. Engineers can explore variations in geometry, materials, boundaries and excitations as well as distribute frequency sweeps. This allows your team to easily optimize designs and perform statistical and sensitivity analyses. antenna array simulated with finite array domain decomposition algorithm; far-field patterns for a variety of scan angles overlaid atop geometry Multiprocessing Licenses Multiprocessing Distributed Solve...
