带声源的IBEM 耦合场分析，为何计算后离散声源个数会增多？
带声源的IBEM 耦合场分析，为何计算后离散声源个数会增多？我数了下大概有100个。我是计算声源作用下弹性结构的声辐射，需要将声源reset，而这么多声源如何reset的啊？并且我只定义一个离散声源，无何计算后会出现这么多，很困惑，特寻求帮助。如sys 5.6 example 中是baffled 模型例子。New Name 'Double Glazed Structure' Model 1 File structure1.sdb Return

可能是没有正确使用baffle命令造成的。我建议你用镜像方法替代baffle试试，请搜索讨论baffle那个帖子。
