+            This method required field line traces to computed beforehand.
+
+        Parameters
+        ----------
+        field_line_plot_name : str
+            Name of the Field Line trace plot as it appears on the GUI project manager tree.
+        field_line_number: list of int, optional
+            List of the lines for which the evaluation will be performed, generated by a previous call to
+            m2d.post.create_fieldplot_line_traces.
+            If None is passed, the inception voltage evaluation is performed for all the created field line traces

+        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_name="LineTracesTest")
+
+        Now you can perform the inception voltage evaluation on all (or a subset of) the created field line traces.
