貌似不行呢 ?是不是穿孔管定义了导纳的条件不能求解声模态吧 ,边界条件设置成use an existing one 求解的时候显示“the duct mode boundary conditions are not supported by this solution,边界条件设置成 no boundary condition set 求解显示”acoustic transfer relation admittance properties are not supported when computing an acoustic mode analsiscase" 各位大神,求指导,是不是必须把定义的传递导纳删除了才能计算哦?
