模态分析
我在进行模态分析的时候，利用命令流导入的方法，就改变了一个参数的尺寸，ansys的计算就明显的慢了，并且没有计算的结果，请高手指教一下，这是怎么回事？还有一个问题：模型建立后，可以进行谐响应分析，但是不能进行模态分析，这又是怎么回事？ 我也不懂。
但建议你最好把命令流贴出来，具体问题才能具体回答 可以进行谐响应分析，但是不能进行模态分析 你用的是什么方法进行的谐响应分析？？ 必须先进行模态分析，在模态分析基础上才能进行谐响应分析。基本过程就搞错了，你的谐响应分析怎么做出来的？ 是不是在进行模态分析时你也选择了求解单元解？
要是不选择单元解的话，速度肯定是慢的，呵呵
另外，楼上说的很，呵呵 谢谢各位帮助，但是我的问题还是没有解决。我还是先说第一个问题，以下是命令流文件，当r=5e-3时有就算的结果，但是当r=10e-3的时候就计算慢，且没有计算结果，实在不知道问题出在什么地方，
