The first parameter on that list is &ldquo;First Iter for Particle Calculation&rdquo; and determines when the source terms from the solution of the fluid momentum equation will go into the particle momentum equation. After this, the source term going into the particle equation changes every iteration, representative of the effect of changing fluid calculations on the particles. This is reasonable for a two-way coupling. However, for a one-way coupling (which I explicitly specify in CFX), I&rsquo;d rather want the source term going into the particle equation from the fluid calculation to not change with iterations. This is because I&rsquo;d already have a converged fluid calculation, before introducing particles into the domain.&lt;\/p&gt;&lt;p&gt;Is such a one-way coupling possible in CFX? If I could bypass the iterative calculations of the fluid momentum equation, that could save time.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-362577","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=\"Mark,If I got this right, the particle solver control parameters you mentioned apply to a two-way coupled simulation.
