Looks like the boundary conditions in your .rea file are somehow messed up. How do you generate you .rea?<br>

> Hi all,<br>

> I keep running into an error whenever I want to use n2to3 to extrude my mesh from 2 dimensions to 3. My workflow is as follows:<br>
><br>
> gmsh .geo file -> gmsh .msh file -> .rea file -> n2to3 > .rea (3D) file.<br>
><br>
> Now if the original 2D .rea file obtained from gmsh contains less than 1000 elements, n2to3 fails with the error<br>
><br>
> At line 651 of file n2to3.f (unit = 10, file = msh_test.rea)<br>
> Fortran runtime error: Bad value during integer read<br>
><br>
> However, should this not be the case (mesh size > 1000) its all smooth sailing. The trouble is with a mesh of that size my processor and memory requirements quickly blow up.<br>

> Incidentally, genmap fails under almost exactly the same conditions.<br>
