I have a model of the negative space here with a defined inlet.

After doing some online research it seems like the &#8220;floating point&#8221; error is usually derivative of a inconclusive value (diving by zero specifically). I&#8217;m not sure how to fix this error. I&#8217;ve changed the fineness of my mesh to .01 and .1, with both having similar problems.
