acoustics FEM,网格是从ANSYS11中导入的，计算时报错！！！！

chourhy

急急急~~~晚辈新手一枚，刚用vitual lab 12做结构振动声辐射计算，碰到如下问题，请各位大神~~前辈指教！！！！！在线等~~~
进入声学有限元模块模拟一块加筋板的振动声辐射计算，采用直接声振耦合计算。结构是一块加筋板，在ansys11中划分网格时板用的是shell63单元、筋（就是一些纵横交错的T型材）用的是beam188 单元。结构和流域的网格模型是导入的ansys11中的.cdb文件，因为.cdb格式的流域壳子在VL中填充不了，所以我将导入VL12的两个cdb文又输出为.bdf格式，然后再导入这两个.bdf格式，此时流域壳子可以填充了。
问题来了~~~~~：在VL12中进行Direct Vibro—Acoustic Response Case (直接声振耦合计算)时，计算机报错，无法计算，显示错误为：“job execution failed .please check job parameters and check that service manager is running on server.”。

直接声振耦合的话，要定义结构网格的材料，单元属性。包括beam单元，检查下这些参数。

主任，我在ansys11中划分结构的网格时就已经定义来结构的单元类型（结构是一个加筋板，板用的shell63，筋用的beam188来模拟）和材料模型，然后用cdwrite,db,,,cdb导入.cdb格式到VL中，在VL中将结构set as structural mesh part。也在VL中重复做了好多遍。临时文件目录那里也改了，但就是依旧报错。前辈能看看我的【job details】的详细描述是什么问题问题么？描述就在我发的这个帖子后面部分

job details里面看不出来。

有时候有些单元属性，导入VL不能正确识别，要重新定义。

请叫我小潘

这个问题是由于从ANSYS中导入的cbd文件中的beam188有问题。VL不能很好的识别
