Change the Initial and Minimum Substeps to 100 and the Maximum Substeps to 1000 and solve.  Does the first substep converge?  If not add a zero to the end of each of those and try to solve again.  If the solution still fails on the first substep, there is something wrong with the model.  It is helpful to type a 3 or 4 into the Newton-Raphson Residuals box and a 1 in the Identify Element Violations box.

Hello, I am trying to solve an fabricated structure ,but somehow I couldn't  get solution

Assuming the first substep converges, it is likely that the solution will fail to converge again at a later time.  When that happens, show the Newton-Raphson Force Residual Convergence Plot under the Solution Information folder.

Solution not convergin
