this is a part of my model
my model is 25*30 and height 15m
when I run that this message clear :
element torsional stiffness GJ/L=1e+01forceBeamcolumn3d::forceBeamcolumn3d
forceBeamcolumn3d--no torsion detected in section,continuing with element torsional stiffness GJ/L=.....
and this message repeat......
also i want to creat a concrete jacketing that jacketed a R/C column
and the slip of the ban of this section is important
now what ELEMENT is suitable ?
very thanks for your consideration

i see where you defined sections 1 and 2,
but you assign torsion only to section 1.
what about section 2?
please pin down which line gives you the error.

check all you braces {} and []

like in the load pattern, for example.

using Crimson editor really helps with that.
