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.
On the Solve/Run tab, in the
Solution Settings group, click the NGF icon.
Ensure the Enable the numerical Green's function check
box is selected.
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.
Add a part or model mesh to the list of static parts.
Click on the relevant part in the 3D view or
model tree.
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.
