标题: 【讨论】请教家族分析问题
mpi提供了自动balance-runner的功能，在相同阵列形式的产品上面是可以得到实现，但是在不同的零件之间能够实现吗？我尝试分析的2个不同零件进行平衡时，总是出现警告，说2个零件的匹配率不同，无法进行下去，请问老斑有做过同样的分析吗？在调入不同零件进入同一个项目进行多模穴分析，是怎样一个操作流程，我的做法是这样的。。调入第一个stl零件==〉+add命令再来调入第二个stl零件==〉修面（这个过程中有很多麻烦，第一个零件跟第二个零件的匹配率没办法一致）==〉设定runner，gate==〉设定材料==〉选择balance runner分析功能进行运算。。出现警告：（Allocating memory for analysis...

** WARNING ** The mesh may have problems. The match ratio is 78 %, and the

请问？：这样的步骤有何欠妥的地方？

FUSION网格的匹配率太低,一般不能低于85%,否则会报警,建议调整网格密度.
