First of all, I would like to express my deepest apologies for the discourtesy of uploading files without a clear understanding of your company&rsquo;s regulations, causing you inconvenience.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Based on what you mentioned, I also believe that at the initial moment when the material breaks into droplets (primary breakup), which is when the VOF-to-DPM operation occurs, the fluid shear should be at its maximum. At this time, the particle&rsquo;s viscosity can be set to infinite Shear Viscosity.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;But if the droplet is successfully represented as a DPM particle, this particle will continue to break up (secondary breakup) according to related literature. Should the viscosity of this particle return to the use of non-Newtonian fluid viscosity at this time? In other words, we must know the shear rate of each particle (parcel) moving in the Eulerian phase in order to calculate the current viscosity through the Carreau Model. But what I am not sure about is how to calculate the shear rate of the particle. The above are my thoughts. Do you think they are correct?&lt;\/p&gt;&lt;p&gt;Returning to my simulation, if I continue to use a non-Newtonian fluid to run VOF-to-DPM, is the current version of Fluent unable to operate? Or do your staff have other methods to troubleshoot the problems I encountered?&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-318184","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=\"Thank you for your reply.
