薄板模态频率相应计算报错3046
错误是：* APPLIED LOADS*** USER FATAL MESSAGE 3046 (SQFREQ)
THIS FREQUENCY RESPONSE ANALYSIS HAS NO EXCITATION SPECIFIED FOR IT.
APPLIED LOADS AND ENFORCED MOTION ARE BOTH NULL.
THE RESULT WILL THEREFORE BE A ZERO SOLUTION.
请高手门帮忙看一下模型中哪里的错误？谢谢！
BDF文件如下，附件里也有一份。

激励没有添加到RLOAD1卡片中 加载的力对应的自由度要放开才能加载，如果是强迫激励的话对应的自由度要约束
