For your first question regarding the sweep, the script &ldquo;pid_grating_coupler_sweep_2D.py&rdquo; is calling a sweep that is defined in the base Lumerical file &#8220;pid_grating_coupler_2D_TE_base .fsp&#8221;. Specifically, if you look at line 85 in the Python script, it uses&nbsp;<a href=\"https:\/\/optics.ansys.com\/hc\/en-us\/articles\/360034931413-runsweep-Script-command\">runsweep &#8211; Script command &ndash; Ansys Optics<\/a> to run the sweep that has previously been defined in the base Lumerical file. So the sweep endpoints are set in the base Lumerical file. On the &lsquo;Optimizations and Sweeps&rsquo; tab, you should see the sweep &lsquo;sweep source position.&rsquo; From there, you can edit the values that are included in the sweep. This is illustrated in the screenshot below:&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&lt;span style=&#8221;mso-no-proof: yes;&#8221;&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/03-12-2024-1733267144-mceclip0.png\" \/>&lt;br&gt;&lt;!&#8211;[endif]&#8211;&gt;&lt;\/span&gt;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;Regarding your second question about running FDTD on a high-performance computer, I can direct you to some resources to get started.
