[Equest-users] Coil curve generating a negative capacity ratio

[Carol Gardner]

Hi Mike,

It will be hard to help you without seeing your .pd2 and .inp files. You
could look around in the .bdl file that was generated to see what you see,
search on error. That will at least show you the area where the error is
occuring.

Good luck,

Carol
