The program chosen initial timestep/load-factor is arbitrary. It is necessary for the user to supply a suitable initial timestep/load-factor through the NSUB or DELTIM command for convergence and overall efficiency.
首先出的是这个警告,因为是静力分析,荷载一步加完,不知道为何出现上述问题。
The calculated reference FORCE CONVERGENCE VALUE = 0 is less than 1E-2 a threshold zero, A value of 1E-2 or specified MINREF is used. Check results carefully.
The calculated reference MOMENT CONVERGENCE VALUE = 6.553089678E-03 is less than 1E-2 a threshold zero, A value of 1E-2 or specified MINREF is used. Check results carefully.
以上两警告是求解时出现的,还是静力分析,为什么还有收敛呢?模型应该没什么问题,我分两种工况加载,其中海冰加载时就没这些问题,但换成海浪就出现了这样的警告,请教下了解海浪的DX是什么原因呢?
谢谢关注,不胜感激!
