Ansys An Internal Solution Magnitude Limit — Was Exceeded

[ u^i+1 = u^i + \Delta u^i ]

Newton-Raphson diverged when stiffness became negative. Displacement DOF at crown exceeded 1e7 mm. ansys an internal solution magnitude limit was exceeded

[ |\Delta u| \approx \frac\lambda_\min ] [ u^i+1 = u^i + \Delta u^i ]

[ [K(u)]u = F(u) ]

where (R) is the residual force vector. As ( \lambda_\min ) approaches zero, even a tiny residual yields enormous displacement increments—triggering the error. ansys an internal solution magnitude limit was exceeded
