TRL Simulation in Designer Interface

Model Description

Full 3D model of a TRL (Transmit Receive Longitudinal) inspection of a steel pipe with water.


Model Geometry

Parametric Variables

The base CAD model was created in Onshape and allows the following design variables to be adjusted. By default the angle of the cuts on the block and the pipe radius are added as configuration variables for quick access through the Configuration Panel in Onshape.

Parametric Variable Description Default Value
wedge_ang Angle of wedge cuts for sensors 162°
pipe_rad Pipe Radius 152 mm
block_ang Angle of main block cut 15°


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

  • Acoustic pressure at nodes along receiver
  • Maximum acoustic pressure field
