Ansys An Internal Solution Magnitude Limit Was Exceeded Access

Newton-Raphson diverged when stiffness became negative. Displacement DOF at crown exceeded 1e7 mm.

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

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: Newton-Raphson diverged when stiffness became negative
