Monte Carlo simulation (also called the Monte Carlo Method or Monte Carlo sampling) is a way to account for risk in decision making and quantitative analysis. The method finds all possible outcomes of your decisions and assesses the impact of risk.
HFSS 3D ModelerThe 3-D interface enables users to model complex 3-D geometry or import CAD geometry. Typically, the 3-D mode is used to model and simulate high-frequency components, such as antennas, RF/microwave components and biomedical devices.
Engineers can extract scattering matrix parameters (S,Y, Z parameters), visualize 3-D electromagnetic fields (near- and far-field), and generate ANSYS Full-Wave SPICE models that link to circuit simulations. The modeler includes parametric capability to easily allow an engineer to define variables and make design variations for design trends, optimization sensitivity and statistical analysis. 3-D models can easily be created using the 3-D solid modeler.Complex multi-layer PCB with overlay of 3-D mesh generated with phi meshing technology. HFSS 3-D LayoutHFSS 3-D Layout is ideal for designers who work in layered geometry or layout of high-speed components, including on-chip embedded passives, IC packages and PCB interconnects.
These types of designs can be easily modeled in the HFSS electrical layout environment while, at the same time, simulating for all 3-D features, such as trace thickness and etching as well as bondwires, solder bumps and solder balls. Geometry such as trace width can be easily parameterized and optimized using the integrated ANSYS Optimetrics tool in the HFSS 3-D layout interface.With HFSS 3-D Layout modeling, material properties, port setup and boundary conditions are set automatically in the layout interface. An advanced phi meshing is included in the 3-D electrical CAD/layout.

ANSYS SI OptionHFSS combined with the ANSYS SI option is ideal for analyzing signal integrity, power integrity and EMI issues caused by shrinking timing and noise margins in PCBs, electronic packages, connectors and other complex electronic interconnects. HFSS with the SI option can handle the complexity of modern interconnect design from die-to-die across ICs, packages, connectors and PCBs.
By leveraging the HFSS advanced electromagnetic-field simulation capability dynamically linked to powerful circuit and system simulation, engineers can understand the performance of high-speed electronic products long before building a prototype in hardware. This approach enables electronics companies to achieve a competitive advantage with faster time to market, reduced costs and improved system performance.The ANSYS SI option adds transient circuit analysis to HFSS. This allows engineers to create high-speed channel designs that include the driving circuitry as well as the channel. The driving circuitry can be transistor level, IBIS-based or ideal sources. When performing an analysis on these channels, a user can select from a variety of analysis types.
ANSYS HFSS software allows calculation of finite-sized phased-array antennas with all electromagnetic effects, including element-to-element coupling, and critical array edge effects.The traditional approach for simulating large phased-array antennas is to approximate antenna behavior by assuming an infinitely large array. In this technique, one or more antenna elements are placed within a unit cell with periodic boundary conditions on the surrounding walls that mirror the fields to create an infinite number of images in two directions. For many years, engineers have used the periodic boundary condition capability in HFSS to simulate infinitely large phased arrays to extract per-element impedance and elemental radiation pattern, including all mutual coupling effects. The method is especially useful for predicting array blind zones that can occur under certain scan conditions. The method, however, is unable to predict behavior of finite-sized arrays that the array edge affects.Far field antenna patterns of finite array calculated with HFSS. Graph on right shows effect of finite array (solid lines) size on sidelobes when compared to infinite array (dashed lines).The finite-sized array simulation technology leverages the repeating nature of array geometries. It can be used with the HPC domain decomposition capability to obtain a very fast solution time for large finite-sized arrays.
This technology makes it possible to perform complete array analysis to predict all mutual coupling, scan impedance, element patterns, array patterns and array edge effects.Phased-array antenna electric field distribution with far-field radiation pattern simulated by finite antenna-array capability in HFSS. A key benefit of HFSS is its automatic adaptive meshing techniques for which you need to specify only geometry, material properties and the desired output. The meshing process uses a highly robust volumetric meshing technique and includes a multi-threading capability that reduces the amount of memory used and speeds simulation time. This proven technology eliminates the complexity of building and refining a finite element mesh and makes advanced numerical analysis practical for all levels of your organization.Automatic adaptive meshing concentrates elements where needed based on field requirements, thus providing an accurate and efficient solution. ANSY HFSS software utilizes tetrahedral mesh elements to determine a solution to a given electromagnetic problem.
These mesh elements in combination with the adaptive mesh procedure create a geometrically conformal, and electromagnetically appropriate, mesh for any arbitrary HFSS simulation. This ensures that HFSS will provide the highest-fidelity result for any given simulation. In addition to creating standard first-order tetrahedral mesh, HFSS can employ zero-order and second-order elements as well as a mixture of elements of different orders. Using mixed-order elements enables HFSS to assign an element order based on the element size, which creates an exceptionally efficient mesh and overall solution process.HFSS also allows the use of curvilinear elements. These elements are perfectly conformal to any associated curved surface. This then provides the highest degree of accuracy possible, as absolutely no assumptions or tessellation are performed.Conformal curvilinear adapted mesh.
