12-结构强度（弹簧拉压）

为什么不能用一个软件 进行呢 也不是每个人 都会三个软件呀 只是个建议

Error encountered in stress recovery. The output will reveal which element has a particular problem. The error is usually due to excessive deformation in the element. Note that this can occur during the iterative process, so that it is not always possible to visualize the excessive deformation. Check the material behavior and the magnitude of the incremental loads. Suggestion : ------------ Activate the cut-back feature if using the AUTO LOAD, AUTO STEP or AUTO INCREMENT solution schemes. This will allow the analysis to automatically cut down the time step and to try again from the end of the last converged increment. For the AUTO LOAD procedure, the increment numbers are maintained as specified in the input. 直接运行作者上传的文件，老有这个错误，什么原因？
