Reply To: Unconverged solution

[John Doyle]

It appears the code is struggling to find force balance.  Rather than specifying a larger NEQIT limit (max allowable number of Newton-Raphson equilibrium iterations per substep), try turning Autotime Stepping ON and specifying many more substeps.  Also, turn on large deflection to include stress stiffening effects.  Perhaps, as a troubleshoot step, try removing the remote force and applying a remote displacement (as a test) to the end of the beam, to assess the relationship between force and displacement for the application.  This can help determine how many substeps you need to achieve convergence with the force based load.
