CAETestBench™ Validation of Simulation

CAETestBench is a process where we validate your simulation against a physical part that has been created and tested using a rigid protocol, which can be accurately replicated in your solver. With this, it is possible to probe the accuracy of the simulation to quantify its ability to replicate real-life simulations. The deformations range from simple tensile modes to more complex, multi-axial modes, impact, and failure.

Why Validate

Physically accurate simulation is a requirement for initiatives such as late-stage prototyping, additive manufacturing and digital twinning. Simulations use mathematical models to replicate physical reality. Verification and validation (V&V) is an important step for high fidelity simulation.

  • Verification is a way to check the accuracy of these models.
  • Factors such as simulation settings, element type, mesh size, choice of material model, the material model parameter conversion process, and quality and suitability of material property data used can also have a large impact on simulation quality. Validation presents a means to check simulation accuracy against a real-life physical experiment.

CAETestBench validations do not use real-life parts, but instead use carefully designed, standardized geometries in a controlled physical test that probes the accuracy of the simulation.

These validations are a valuable tool to measure solver accuracy prior to use in product applications. Confidence is gained that the simulation replicates real-life physical behavior.

Validate before you create



What we do

  • We use the PICSCI platform to set up experiments and simulations.
  • We create the part and set up and perform the physical test. The data is dropped into CAETestBench.PICSCI.
  • We now set up the simulation and record simulation parameters and variables in CAETestBench.PICSCI.
  • We perform the simulation, then drop the simulation outputs into CAETestBench.PICSCI.
  • Using the PICSCI Analyzer module, we automatically compare and cross plot physical test to simulation results. A measure of simulation accuracy is obtained.
  • We iterate as needed to explore the best material models and simulation parameters
  • We deliver to client
    • Validations against experiment
    • Simulation methods
    • Simulation file
    • CAE Material file(s)


Simulate with confidence

CAETestBench validation provides a measure of simulation accuracy for the chosen element type and size, material models, and simulation parameters.

If you change your simulation parameters, element configuration, or material model, you can re-validate to assess the impact on your simulation.

  • Go to CAETestBench
  • Make a copy of the simulation you want to modify
  • Download the simulation file and material card
  • Modify inputs Run simulation
  • Upload new simulation data, parameters and variables
  • Use Analyzer module to compare simulation to experiment
  • Iterate as needed to explore best material models and parameters
