Using the Numerical Green's Function to Reduce CPU Time

For a method of moments (MoM) model, specify the static part. The part is saved and locked to prevent modification. Save the static interaction matrix to a .ngf file and reuse the file.

  1. On the Solve/Run tab, in the Solution Settings group, click the  NGF icon.
    Figure 1. The Numerical Green's Function (NGF) Settings dialog.

  2. Ensure the Enable the numerical Green's function check box is selected.
  3. To lock the static part, ensure the Lock static parts check box is selected.
    Note: A locked part cannot be modified or deleted. If the frequency is changed or face properties are modified, it is recommended to unlock and remesh the part.
  4. Add a part or model mesh to the list of static parts.
    1. Click on the relevant part in the 3D view or model tree.
  5. Click OK to close the dialog.
    The static part is locked and cannot be modified. An active NGF part is indicated by the icon in the model tree.
    Note: To disable the NGF for a part, clear the Enable the numerical Green's function check box.
