Solving Faces with Large Element Physical Optics (LE-PO)

To solve a model with large element physical optics (LE-PO), you must activate LE-PO for each relevant face.

  1. Select the face(s) in the 3D view or in the details tree that you want to solve with LE-PO.
  2. In the details tree, from the right-click context menu, select Properties.
  3. On the Modify Face dialog, click the Solution tab.
  4. Under Solve with special solution method, from the drop-down list, select one of the following:
    • To use complete ray tracing, select Large element PO - full ray-tracing.
    • If the assumption can be made that all triangles on which the PO approximation is made, are illuminated, select Large element PO - always illuminated. Ray-tracing is switched off to reduce run time.
    • To use full ray tracing when the metallic triangles are only illuminated from the front (normals side), select Large element PO - only illuminated from front.
  5. Click OK to save the face properties and to close the dialog.
