I see far too many high aspect ratio cells as everyone takes the y+ bit of their CFD training far too seriously and never considers the resulting cell shape.&nbsp;&lt;\/p&gt;&lt;p&gt;Drop the Time Scale Factor. I suspect &#8220;something&#8221; ie boiling is occurring too quickly and that&#8217;s causing problems for the solver.
