<p>Hi Philipp,</p>
<p>Glad to hear that some people use mesh2d. I know we have to
improve the error message by getting the numbers at the Fortran
level... There is also other errors which are not easy to fix
without knowing the number of the problematic point (point too
close to the boundary, for example). Can you file a bug on BZ ?</p>

<div>Dear all,</div>
<div><br>
</div>
<div>using the mesh2d - function I get an error: mesh2di:
some points are identical.</div>
<div><br>
</div>
<div><br>
</div>
<div>How to identify these points and remove the duplicates?</div>
<div><br>
</div>
<div>There are roughly 500'000 coordinates....</div>
<div><br>
</div>
<div>Thank you,</div>
