To present noise contours of noise levels is is necessary to develop calculation grids.  In PEN3D these are called calculation boxes.  This example shows how to develop an array of smart calculation boxes for a complex road traffic model.  The grid mesh is generated along the road and close to objects so the highly variable noise levels close to barriers are exposed.

  • PEN3D: CoRTN calculation grids
  • Skills Needed: Advanced technique to generate smooth contouring output
