For very low-frequency method of moments (MoM) solutions, enable low-frequency stabilisation to
ensure a valid solution over the full frequency range.
On the Solve/Run tab, in the
Solution Settings group, click the Solver Settings icon.
On the Solver Settings dialog, click the
General tab.
Under Low frequency modelling, select the
Activate low frequency stabilisation for MoM check
box. From the drop-down list, select one of the
following:
Auto
This option allows the Solver to
determine automatically if the low frequency stabilisation should be
used for the model.
Always on
This option enables the low frequency stabilisation for the
model.
