<p>Dear Gmsh community,</p>
<p>like in this previous post on this mailing list <a
href="http://onelab.info/pipermail/gmsh/2017/011809.html">(http://onelab.info/pipermail/gmsh/2017/011809.html),</a></p>
<p>I have a tree-like geometry, consisting of a union cylinders and
spheres, and I'd like to cut it out of a box.</p>
<p>The problem mentioned in this post in 2017 still seems to persist
in Gmsh 4.2.3.</p>
<p>I've been trying to subtract a lot of cylinders and spheres from
a box geometry. It works for a small amount of cylinders but
refuses to work for many geometries. The error message is simply <br>
</p>
<p>Error : Intersection operation cannot be performed<br>
Error : 'tree.geo', line 3480 : Could not apply boolean operator<br>
</p>
<p>I attached the geo file. Any idea what the problem is? Is there
some kind of internal limit on how many geometry objects can
participate in boolean operations?</p>
<p>Thank you for your help</p>
<p>Timo<br>
