Unrealistically Large Results in STEEL Warping Torsion Due to Incorrect Boundary Conditions or Imperfection Setting

The results from STEEL Warping Torsion seem far too great to me. What could be the reason?

Answer:

Please check the boundary conditions; that is, the definition of nodal supports and especially the application of the imperfection in Window 1.13 "Parameters – Member Sets". The imperfection is preset as L/150, which can represent a conservative solution.
