我在算一个橡胶筒的模型,但是每次计算到第二个载荷步的时候都算不走,出现相同的警告:
There is zero MOMENT everywhere in the model based on the default criterion. please check the value of the average MOMENT during the current iteration to verify that the MOMENT is small enough to be treated as zero. if not, please use the solution controls to reset the criterion for zero MOMENT.
模型只受轴向压缩力,不知道怎么回事,请各位指教!
