<p>Hi Marton, <\/p><p>You are welcome! These solvers are slightly more complicated to use than FDE, but I am pretty sure you can learn them. If the dimensions, and especially the length of the waveguides are a few microns (only a few times greater than the wavelength), then I will recommend using FDTD. But if these waveguides are extremely long (hundreds of microns), then EME will be more suitable, as FDTD will require a large amount of compute power. Ansys offers short introductory courses on these solvers. You can find them at Ansys Innovation Courses: Ansys Innovation Courses<\/a>. When you visit the page, you can select the category as “Photonics<\/strong>” to see a list of all availabe courses. From there, you can find both FDTD and EME<\/strong>. These videos are pretty short and easy to understand but I think they will be a food place to get some familiarity with the solvers. The we can discuss setting up your simulation.<\/p><p>Regards,<br>Amrita<\/p><\/p>\n","protected":false},"template":"","class_list":["post-356730","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
