Ansys An Internal Solution Magnitude Limit Was Exceeded -

[ [K_T^i]\Delta u^i = F_ext - F_int^i ]

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

where ([K]) is the stiffness matrix (dependent on displacement (u) in nonlinear cases), (u) the displacement vector, and (F) the applied load. The Newton-Raphson method iteratively solves: ansys an internal solution magnitude limit was exceeded

[ |\Delta u| \approx \frac\lambda_\min ] [ [K_T^i]\Delta u^i = F_ext - F_int^i ]

Newton-Raphson diverged when stiffness became negative. Displacement DOF at crown exceeded 1e7 mm. (u) the displacement vector
