+
+        .. note::
+            This method requires field line traces to be computed beforehand.
+
+        Parameters
+        ----------
+        plot_name : str
+            Name of the field fine trace plot as it appears in the AEDT GUI project manager tree.
+        field_line_number: list of int, optional
+            List of line objects on which the evaluation will be performed.
+            If the field line traces plot does not exist, this can be created with ``app.post.create_fieldplot_line_traces``.
+            The default value is ``None``, in which case the inception voltage evaluation will be carried out for all existing field line traces.
+
+        Returns
+        -------
+        bool
+            ``True`` when successful.
+
+        References
+        ----------
+        >>> oModule.EvaluateInceptionVoltage
+
+        Examples
+        --------
+        Create an instance of Maxwell and link to a project named
+        ``projectname``. If this project does not exist, create one with
+        this name.
+
+        >>> from ansys.aedt.core import Maxwell2d
+        >>> m2d = Maxwell2d(project_name)
+
+        Create a field line traces plot in the Region from seeding faces (insulator faces).
+        >>> plot = m2d.post.create_fieldplot_line_traces(
+        >>> seeding_faces = (["Ground", "Electrode", "Region"],)
+        >>> in_volume_tracing_objs = (["Region"],)
+        >>> plot_name="LineTracesTest")
+
+        Now the inception voltage evaluation can be performed on all (or a subset) of the created field line traces.
+        >>> m2d.post.evaluate_inception_voltage(plot_name=plot.name, field_line_number=[1, 2, 4])
