Full Matrix Capture 2D - CAD


Snapshot of acoustic pressure showing wave interaction with defect


2D model to simulate a Full Matrix Capture (FMC) data collection of a stainless steel block containing a circular defect. Simulations are run in parallel for transmitting on each of the array elements to generate the full FMC dataset.


Basic Model Schematic

Parametric Variables

The base CAD model was created in Onshape and allows for the following design variables to be adjusted. By default the number of elements, defect radius, and defect x/y location are added as configuration variables for quick access through the Configuration Panel in Onshape.

Parametric Variable Description Default Value
narelem Number of array elements 8
def_rad Radius of circle defect 0.2 mm
def_x X position of defect 8.9 mm
def_y Y position of defect 5 mm


Here are a list of the types of outputs to expect from this model:

  • Time Histories (XY Graphs)
    • Drive input signal
    • Acoustic pressure at the center of each array element
  • Maximum acoustic pressure data array
