Rectangular fiber section

[gsdeshmukh]

Dear Friends
I'm trying to give inputs to fiber section to be used as beam. as shown in fig 1.

Fig 1

STKO .jpg (122.05 KiB) Viewed 1690 times

when i insert all required data in form and save it, the section where red ? is placed, i cant see graphical view of data.
is there anything wrong with it ?

Also Had this in terminal window

I created one fresh section and then i cloned it to other. Is it the reason for this red error ?

[STKO Team]

There is an error in the computation of the automatic confinement.
Are you sure the numbers for stirrups are consistent with the rest of the section?

[gsdeshmukh]

The problem is solved.
I used clone command to create new fiber model.
Instead of that i modelled it as a fresh and all errors resolved automatically.
The fiber model is small as i used unit of lengths as meters and that of forces as kN, due to which it was looking so smal, when i zoomed in after modelling it fresh, i can see that too.

Thanks for reply.

Actually, the drawing of the section should zoom automatically. If it doesn't, it means that something was left as default (in mm) and it's much larger then others.
