I have a problem in modeling a channel section as a fiber section.
Actually some numerical errors would be appear in black window which is not clear for me such as the following errors:
error
5.88888 16.3287
5.88888 13.2689
6.48795 15.3687
. .

. .
I would be thankful if you help me to find this.

thanks alot
