<div dir="ltr"><div>Dear all, <br></div><div><br></div><div>I'm writing to you because I need some tips/advices for mesh refinement. <span lang="en"><span>Given a simple model like
the one attached to this mail, If the spacing for material 1 is d1 =
300 m, and for material 2 it is d2 = 220 m.</span> <span>How to define the spacing for points p1, p2, p3, p4, p5, p6?</span> <span>How to refine near points p7, p8, ...., p14?</span> <span>For these points, I want a refinement equal to d1/20 and that extends up to 80 m from each point.</span><br><br><span>I
have already done experiments but it is not clear to me how to handle
the attractor option, namely I don't know if following lines are
