Mechanics & Acoustics

Nonlinear Propagation

Observe the formation of shock-waves and harmonics as high-amplitude waves propagate through nonlinear materials.

Nonlinear Geometry

Capture the changes in material properties under large deformation conditions, where forces move with the updated geometry.

Contact and Impact

Sophisticated non-linear contact capabilities for simulating impact, large deformation contact and delamination/debonding effects.

Element Erosion

Under highly dynamic conditions, elements can be removed from the calculation to represent penetration or intense compression.

Fully Elasto Dynamic

Supports all wave-types, including mode conversion and arbitrary interfaces and effects of sub-wavelength objects.

Arbitrary Loads

Specify multiple, arbitrary time-dependent drives for realistic loading conditions. Arbitrary phasing can be applied for full array simulation.

Couple Fluids and Solids

No need to specify separate domains for fluids and elastic materials. Interfaces and physics are captured in the solver automatically.

Steady State Flow

Simulate the effects of background flow fields on the propagation of ultrasonic waves. Supports time-dependent flow profiles from CFD.

Thermo-Mechanical

Explore heating in your system and observe thermal changes on mechanical stresses. See how components deform under temperature.

Sophisticated Boundary Conditions

Linear and nonlinear wave-types are handled at model boundaries. Absorbers satisfy infinite load conditions for transient waves.

Piezoelectric Capabilities

Fully Coupled Electromechanics

Capture direct and indirect piezoelectric effects. Solver seamlessly integrated with fluid and elastic materials.

Electrical Circuits

Include effects of electrical components directly in FEA analysis. Multiple arbitrary circuits can be assigned to electric boundary conditions.

Full Tensor Properties

Supports all crystal symmetries and cuts. Mechanical stiffness or compliance, piezoelectric stress or strain entries.

Voltage & Current Drives

Drive electromechanical systems with user-defined functions, either with voltage or current, or via circuit components.

Arbitrary Poling

Pole piezoelectric materials in any direction or angle required. Rotate the tensors to create updated properties for unique cuts.

Large Deformation

Capture the geometric and poling direction changes incurred when piezoelectric materials are subject to large strains (>1%).

Thin Film Layers

Incorporate thin piezoelectric and electrode layers (sub-wavelength) accurately. Analyse performance of thin resonators.

Material Property Optimisation

Extract optimised piezoelectric properties from measured electrical impedance response for high-accuracy simulations.

Frequency Dependent Damping

Specify bulk and shear damping values to support accurate material performance over broadband ranges.

Electrostatics

Combine nonlinear electric fields and geometric effects to capture electrostatic behaviour for capacitive systems and devices.

Core Solvers

Efficient Memory

Optimised routines compress memory usage to enable multi-million element models to run in less than a GB of RAM.

Ultra-Fast Solvers

Unique approach to transient FEA allows large models to be solved orders of magnitude faster than more general FEA methods.

Multi-Billion Element Models

Include entire systems in simulations to reduce approximation and capture highly-coupled, complex effects in a single run.

MPI Routines

Take advantage of domain decomposition methods to spread the computation across 100s or 1000s of cores.

SMP Compatible

Take advantage of excellent SMP processing benefits to reduce simulation time in proportion to the number of cores available.

Hybrid Methods

Combine high-fidelity FEA for complex analysis, and fast analytical methods for routine analysis, for a more effective approach.

Batch Analysis

Automate and accelerate tasks and analysis through powerful scripting and batch simulation features. Enables large DoE runs with ease.

Geometry Creation & Import

CAD Import

Import from a range of formats directly into PZFlex. Create complex models with ease and rapidly simulate.

Meshing

Automatic meshing of Importation formats takes the burden off the user and accelerates the model workflow.

Other FEA Models

Save time by utilising meshes from existing software packages and import them directly, with minimal manipulation required.

500 Example Models

Take advantage of industry specific examples to accelerate your model building expertise and getting tangible results fast.

CT & MRI

Assign materials using 2D and 3D arrays to import complex geometries from MRI, CT and other voxel based formats.

Parametric Primitives

Rapidly iterate through designs with minimal effort through scripted primitives. Control variables easily with CSV formats.

Visualization & Postprocessing

Visual Control

Rotate, zoom, manipulate and view your models and results in their native format using built-in tools to asses dataset faster.

Runtime Graphics

Monitor simulation metrics during runtime to easily assess convergence, performance and accuracy of models with 2D and 3D plots.

Large Models

Visualise large native PZFlex models and results without high-end graphics engines to get the most out of your data without extensive manipulation.

Surface, Contour & Cutting

Go deeper into your data with advanced processing tools and options to help provide insights quickly and easily.

Animations

Capture time-varying data fields and easily compile into presentable animation formats in both runtime and post-processing.

Material Blanking

Understand and verify your structures better by only plotting materials and data fields that are relevant to your analysis.

Exportation

Export data to popular 3rd party tools such as matlab, python and VTK to facilitate more user specific analysis, visualisation and processing requirements.

Specialised Metrics

Industry specific export options such as: Electrical Impedance, Admittance, Conductance, TVR, S-parameters, Beam profiles, Deformation plots and more.
