求解下图语句的意思
本帖最后由 sjwluobo 于 2012-7-8 20:52 编辑我在做时程分析时,发现运行若干步以后出现收敛困难,然后输出窗口有如图所示的语句:
然后出现错误:
*** ERROR *** SUPPRESSED MESSAGE CP = 127.391 TIME= 11:18:17
Preconditioned conjugate gradient solver error level 1.Possibly, the
model is unconstrained or additional iterations may be needed.Try
running with a multiplier MULT > 1 in EQSLV command (3 > MULT > 1).
求高手给解释一下错误的原因好吗?
