The nlgeom flag was not active
WebThe nlgeom flag was not active in the previous general (non-perturbation) step. The activation of nlgeom in the current step may cause convergence problems if the displacements at the end of the previous general step are not small. Discontinuities in displacement response histories should also be expected. WebToggle Nlgeom Off to perform a geometrically linear analysis during the current step. Toggle Nlgeom On to indicate that Abaqus/Standard should account for geometric nonlinearity during the step. Once you have toggled Nlgeom on, it will be active during all subsequent steps in the analysis.
