Local Mesh Properties in CST MWS

In the dialog of local mesh properties, we can increase or decrease the values of Dx, Dy and Dz to modify the mesh density. According to the document, the setting Extend x/y/z range is used to extending the maximum step width outside the bounding box of this structure element by the range given. But is it likely that the setting Extend x/y/z range impacts the mesh density?In which situation Extend x/y/z range is necessary to be set?

局部加密啊

我不清楚你所說的“影響”是什么意思。既然是在網格參數設置屬性里，調整每一個參數都會改變"Mesh Density"，否則設置這個參數做什么呢?
Situation：需要把local mesh設置的參數"extend"到“局部結構”的"bounding box"之外的空間的時候。

yeah！we can increase the values of Dx, Dy and Dz to define the maximum step width of the object！
1)Of course ,the setting Extend x/y/z range impacts the mesh density！
The setting Extend x/y/z range define the Neighbouring boundary space Dx, Dy and Dz of your object ！
2)Especially PEC ,the Neighbouring boundary space Dx, Dy and Dz is much important .You can set Extend x/y/z range in this situation！

Thanks for your help. Euh but ..for which type of structure that we need to extend its local mesh maximum step width outside the bounding box of this structure space?

Thank you. And the larger value Extend x/y/z range by has , the more intense the corresponding mesh will become? Are they in proportion?

沒有什么規定的形狀，如果金屬邊緣以外的部份是“重要區域”，那就需要，比如耦合傳輸線之間的空間。

Thank you
euh..
The dimension of Dx/Dy/Dz or Extending x/y/z range is proportional to the density mesh?

1)YES ！ For example ,if I set extend x range 20 the result is just in the X direction of the EXtend vaule of 20
2)You should know the meaning of Extend x/y/z range

Aha, thank you
