Dear Dr. Henshaw,
I am using Overture to generate interpolation data for a chimera grid
having 3-dimensional stator blade and a background domain. Ogen aborts with
the following error message.
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff105a162 in ?? () from /lib/x86_64-linux-gnu/libc.so.6
GDB reports that there is a problem in setting the hole width:

To try a simpler problem, I used a cylinder inside the same background grid
instead of the stator blade and in this case it works fine and
interpolation data and hole cut both are fine. The content of the command
file is:

Based on the above information, would you be able to suggest me something
that I should try in order to get Ogen working for a 3-Dimensional variable
cross-sectional blade in a background domain. If you want any other
information please let me know. Thanks.
