Otherwise, the geometric nonlinearity will not be considered. WebAn extension of the NLGEOM-gravity method to a spherical FE model, where gravity must be implemented in the form of body forces combined with initial stress, leads to a divergence of the solution when viscous behaviour is turned on. We thus conclude that the applicability of the NLGEOM method is so far limited to flat FE models, and in 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. tear shop
