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
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
Post Processor Outputs
|Model Size||177364 elements|
|Solve Time||99 s (2 CPU)|
|Memory Usage||13 MB|
|Recommended CPU configuration||2 CPU|
