The time of day for a transient simulation is the starting time plus the flow-time. For mesh orientation, you will need to specify the North and East direction vector in the CFD mesh. The default solar irradiation method is Fair Weather Conditions. Alternatively, you can choose the Theoretical Maximum method. The sunshine factor is simply a linear reduction factor for the computed incident load that allows for cloud cover to be accounted for, if appropriate.&lt;\/span&gt;&lt;\/p&gt;&lt;p style=&#8221;background: #FEFEFE; box-sizing: inherit; margin: 1rem; text-rendering: optimizelegibility; font-variant-ligatures: normal; font-variant-caps: normal; orphans: 2; text-align: start; widows: 2; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; word-spacing: 0px;&#8221;&gt;&lt;span style=&#8221;font-family: &#8216;Source Sans Pro&#8217;,sans-serif; color: #0a0a0a;&#8221;&gt;You can specify these inputs in the&nbsp;&lt;strong style=&#8221;box-sizing: inherit; line-height: inherit;&#8221;&gt;&lt;span style=&#8221;font-family: &#8216;Source Sans Pro&#8217;,sans-serif;&#8221;&gt;&lt;span style=&#8221;box-sizing: inherit;&#8221;&gt;Solar Calculator&lt;\/span&gt;&lt;\/span&gt;<\/strong>&nbsp;dialog box that is accessible from the&nbsp;&lt;strong style=&#8221;box-sizing: inherit; line-height: inherit;&#8221;&gt;&lt;span style=&#8221;font-family: &#8216;Source Sans Pro&#8217;,sans-serif;&#8221;&gt;&lt;span style=&#8221;box-sizing: inherit;&#8221;&gt;Radiation Model&lt;\/span&gt;&lt;\/span&gt;<\/strong> dialog box.&lt;\/span&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-346352","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Fluent provides a solar calculator that can be used to compute solar beam direction and irradiation for a given time, date, and position.
