NASRAN报错

*** USER FATAL MESSAGE 9050 (SUBDMAP SEKRRS)

这种9050还是第一次碰到。这是计算万向节实体网格的动刚度时遇见的，怎么改都是这个错误，有没有大神能解度一下

英文提示不是说的很清楚了？
SET F1<=0. 有两种方式：
1、ON THE EIGR BULK DATA ENTRY OR V1<=0. ON THE EIGRL ENTRY.
2、IF IT IS DESIRED TO EXCLUDE RIGID BODY OR LOW FREQUENCY MODES FROM DYNAMIC SOLUTION THEN SPECIFY PARAM,LFREQ OR MODESELECT CASE CONTROL COMMAND
