计算中有如下错误：
error-zero on diagonal in jacobi iteration
row 18 of 19 values 9.494424e -1.168731e-22 swp/iter
error-a problem has been encounted while solving for modes(j3)
try adding 10 more modes to the cutoff modes or try determinant search
method by entering:set solution incore command before any loads.
请问这个问题 怎么解决？

这是说程序进行动力分析求解时，雅克比行列式遇到错误，您可以通过增加求解振型或者使用set solution incore 命令来解决

振型太多也可能有这个提示,我算个单层平面框架,振型数取9,6都这样,改到3就可以了.
