Flow convergence can be accelerated if a better initial solution is used at the start of the calculation. The Full Multigrid initialization (FMG in&lt;span class=&#8221;&rdquo;highlight&rdquo;&#8221;&gt;itial&lt;\/span&gt;ization) can provide this initial and approximate solution at a minimum cost to the overall computational expense. other you can try using real gas property table (RGP).&nbsp;&lt;\/p&gt;&lt;p&gt;You can refer to fluent user&rsquo;s guide for more on FMG initilization: <a href=\"https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v231\/en\/flu_ug\/flu_ug_sec_fmg_multigrid.html?q=FMG%20initial\">33.10.
