一、HFSS 3D

Direct Solver Option: Advanced Phased Array Antenna Ana lysis

Concurrent Initial Meshing for 3D Component Array + Hybrid Solver

• All 3D components + native regions are meshed concurrently ‐ Near linear speedup when components are of similar mesh complexity 

• Set “Do Mesh Assembly” ‐ Auto HPC will engage parallel component meshing when set ‐ Manual HPC requires set “Mesh Assembly” in Job Distribution

5G Standard Toolkit

• Codebook import 

• Power Density Calculation 

• Cumulative Distribution Function 

• Fully Parameterized

5G antenna array performance modeling 

Beam Steering Code Book 

Evaluating spatial coverage capability for 5G mm-wave antennas 

• Cumulative Distribution Function (CDF) for Antenna Arrays 

Statistical an alysis of far field quantities that results in the probability that a quantity will be less than or equal to a certain percentage over the entire infinite far field sphere 

• Post processing CDF in ANSYS Electronics Desktop (AEDT) 

ACT Extension developed to automatically extract CDF curve for antenna arrays with multiple weightings 

Evaluating human body effects on CDF 

Distributed Direct Solver – Memory Improvement 

•Multi-package module 264 ports 

•Multi-package module 764 ports 

IC Package model, 34.5M matrix unknowns 

2020 R1 

            Adaptive Meshing 

            Elapsed time: 04:12:25, total memory: 552.4 GB 

            Frequency Sweep 

            Elapsed time: 07:32:11 

2020 R2 

            Adaptive Meshing 

            Elapsed time: 02:48:27, total memory: 421.6 GB (24% savings)  

            Frequency Sweep (More Freq points in II) 

            Elapsed time: 05:53:59 (22% faster)

Allow Metal and Dielectric IE Regions to Touch in Presence of FEBI [Beta] 

• New hybrid solver option useful for car fascia mode ling ‐ Convenience and performance improvements compared with FEBI ‐ Beta flag: “Mixed IE Region Solver”

Near Field An alysis for SBR+ 

• Near field support for both SBR+ design and hybrid design with SBR+ regions 

• Supports overlay to the modeler window 

SBR+ Near-fields

• 1 GHz monopole on frigate 

• High fields between  antenna and bridge 

• Standing waves captured 

Release of Ansys HFSS Multipaction Solver

• New in 2020 R2 Auto-solving and Charged Particle Visualization

Enhanced Shell Element Implementation

• New implementation much more robust especially for “dirty” geometry ‐ Several models that failed in 2020 R1 now work 

• Solver will issue information to mesh feedback tool when integrity of mesh is unclear ‐ Example: T-junctions are flagged for inspection as it could be valid geometry or poor mesh
