<p>[QUOTE=&quot;-jeffB, post: 7500105, member: 27832&quot;]I can&#039;t help thinking that you&#039;re working too hard here. Don&#039;t model the planchet as a flowing fluid. Think of it as a solid object being hit by a more-solid object, and <i>deforming</i> as a result. From the engineers I roomed with and dated and married, I got the <i>impression</i> that Deformables and Fluid Dynamics use different approaches.</p><p><br /></p><p>Sure, it&#039;s hard to think of the short distance flow within the planchet as turbulent -- and it&#039;s <i>not useful</i>. Wrong model. What&#039;s the right model? You have the right idea in your last paragraph: ask a metallurgist.[/QUOTE]</p><p><br /></p>
