[Gmsh] error during MESH

[Gianangelo Bracco]

Dear all
I am testing a model changing the parameter r of the enclosed geo file.
with r=1.15 I got the following errors during  MESH, for smaller values
(1.10 and 1.30, 1.45 no errors)
--------------------------------
...Meshing 2D surface 23
Error 3 identical point in Qtest
--------------------------------------



and at the end of the procedure
 


--------------------------------------------------
Error
Mesh generator error summary
0 warnings
1 error
Check the full log for details 
-----------------------------------------------

best wishes
