Shell warning error - To allow the shell to complete, the level of checking between pairs of faces has been reduced. downstream operations that use this shell's geometry may have problems.

hi,

New to using shells at work and ive just got this error message pop up and I was wondering what was causing it and how i could fix it?

'To allow the shell to complete, the level of checking between pairs of faces has been reduced. downstream operations that use this shell's geometry may have problems.'

Thanks in advance

Joe
