Software Features & Specifications

PZFlex lets engineers model and simulate a wide range of physics with an emphasis on wave-propagation and piezoelectric applications.

With its custom FEA solvers you can tackle large problems in ultra-fast timescales, allowing you to iterate quickly to the optimal solution. 2D models run in seconds, 3D models in minutes. Efficient use of RAM ensures users can access classes of FEA models that were previously reserved for HPC systems.

The baseline product includes a range of GUI interfaces for model construction, importation and post-processing. With Multiphysics capabilities included in the package, users can access a wide range of effects without purchasing additional modules.

PZFlex Features & Specifications

  1. Nonlinear Propagation: Observe the formation of shock-waves and harmonics as high-amplitude waves propagate through nonlinear materials.
  2. Nonlinear Geometry: Capture the changes in material properties under large deformation conditions, where forces move with the updated geometry.
  3. Contact and Impact: Sophisticated non-linear contact capabilities for simulating impact, large deformation contact and delamination/debonding effects.
  4. Element Erosion: Under highly dynamic conditions, elements can be removed from the calculation to represent penetration or intense compression.
  5. Fully Elasto Dynamic: Supports all wave-types, including mode conversion and arbitrary interfaces and effects of sub-wavelength objects.
  6. Arbitrary Loads: Specify multiple, arbitrary time-dependent drives for realistic loading conditions. Arbitrary phasing can be applied for full array simulation.
  7. Couple Fluids and Solids: No need to specify separate domains for fluids and elastic materials. Interfaces and physics are captured in the solver automatically.
  8. Steady State Flow: Simulate the effects of background flow fields on the propagation of ultrasonic waves. Supports time-dependent flow profiles from CFD.
  9. Thermo-Mechanical: Explore heating in your system and observe thermal changes on mechanical stresses. See how components deform under temperature.
  10. Sophisticated Boundary Conditions: Linear and nonlinear wave-types are handled at model boundaries. Absorbers satisfy infinite load conditions for transient waves.
  1. Fully Coupled Electromechanics: Capture direct and indirect piezoelectric effects. Solver seamlessly integrated with fluid and elastic materials.
  2. Electrical Circuits: Include effects of electrical components directly in FEA analysis. Multiple arbitrary circuits can be assigned to electric boundary conditions.
  3. Full Tensor Properties: Supports all crystal symmetries and cuts. Mechanical stiffness or compliance, piezoelectric stress or strain entries.
  4. Voltage & Current Drives: Drive electromechanical systems with user-defined functions, either with voltage or current, or via circuit components.
  5. Arbitrary Poling: Pole piezoelectric materials in any direction or angle required. Rotate the tensors to create updated properties for unique cuts.
  6. Large Deformation: Capture the geometric and poling direction changes incurred when piezoelectric materials are subject to large strains (>1%).
  7. Thin Film Layers: Incorporate thin piezoelectric and electrode layers (sub-wavelength) accurately. Analyse performance of thin resonators.
  8. Material Property Optimisation: Extract optimised piezoelectric properties from measured electrical impedance response for high-accuracy simulations.
  9. Frequency Dependent Damping: Specify bulk and shear damping values to support accurate material performance over broadband ranges.
  10. Electrostatics: Combine nonlinear electric fields and geometric effects to capture electrostatic behaviour for capacitive systems and devices.
  1. Efficient Memory: Optimised routines compress memory usage to enable multi-million element models to run in less than a GB of RAM.
  2. Ultra-Fast Solvers: Unique approach to transient FEA allows large models to be solved orders of magnitude faster than more general FEA methods.
  3. Multi-Billion Element Models: Include entire systems in simulations to reduce approximation and capture highly-coupled, complex effects in a single run.
  4. MPI Routines: No need to specify separate domains for fluids and elastic materials. Interfaces and physics are captured in the solver automatically.
  5. SMP Compatible: Take advantage of excellent SMP processing benefits to reduce simulation time in proportion to the number of cores available.
  6. Hybrid Methods: Combine high-fidelity FEA for complex analysis, and fast analytical methods for routine analysis, for a more effective approach.
  7. Batch Analysis: Automate and accelerate tasks and analysis through powerful scripting and batch simulation features. Enables large DoE runs with ease.
  1. CAD Import: Import from a range of formats directly into PZFlex. Create complex models with ease and rapidly simulate.
  2. Meshing: Automatic meshing of Importation formats takes the burden off the user and accelerates the model workflow.
  3. Other FEA Models: Save time by utilising meshes from existing software packages and import them directly, with minimal manipulation required.
  4. Image Importation: Allocate materials by color and quickly create complex structures in FEA with minimal handling. Various formats supported.
  5. CT & MRI: Assign materials using 2D and 3D arrays to import complex geometries from MRI, CT and other voxel based formats.
  6. Parametric Primitives: Rapidly iterate through designs with minimal effort through scripted primitives. Control variables easily with CSV formats.
  7. GUI Wizards: Perform full simulations and detailed post-processing of common models through easy-to-use wizard interfaces.
  8. 500 Example Models: Take advantage of industry specific examples to accelerate your model building expertise and getting tangible results fast.
