But I still have a question. Firstly, the additional issue I face is that the WG I simulate with MODE is oriented along the x-axis (injection x-axis). To use overlap, I need the elliptical beam in the Y-Z plane. Of course, I can rearrange the WG geometry, but I wanted to find out if there is a way to generate an elliptical beam in the Y-Z plane.&lt;\/p&gt;&lt;p&gt;Concerning zbf, it seems that the zbf export works in a way that the resulting field distribution is in the X-Y plane. Actually, I tried this approach by following the tutorial: &#8220;Import Source in Ansys Lumerical FDTD&#8221; (<a href=\"\/courses\/index.php\/courses\/lumerical-fdtd-sources\/lessons\/import-source-in-ansys-lumerical-fdtd-lesson-7\/\" target=\"_new\" rel=\"noopener\">&lt;span style=&#8221;color: windowtext; text-decoration: none; text-underline: none;&#8221;&gt;\/courses\/index.php\/courses\/lumerical-fdtd-sources\/lessons\/import-source-in-ansys-lumerical-fdtd-lesson-7\/&lt;\/span&gt;<\/a>). I defined the source and the monitor so that x is the injection direction and saved the field from the monitor to the zbf. However, when I import it to the DECK in MODE for the overlap analysis, the field is in the X-Y plane.&lt;\/p&gt;&lt;p&gt;Is there is a way to get field in zbf in Y-Z plane ? &lt;span style=&#8221;mso-spacerun: yes;&#8221;&gt;&nbsp;&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;Thank you in advance!&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-289731","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/289731","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/289731\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=289731"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
