CST網(wǎng)格劃分為什么有些紅點(diǎn)不經(jīng)過(guò)線
圖片中綠色為有耗金屬,紫色是空氣,為什么有些紅點(diǎn)沒(méi)有線經(jīng)過(guò)呢,還有像第二幅圖中那種情況,兩個(gè)綠色的條狀金屬會(huì)因?yàn)檫吘壴谝粋€(gè)格子中出現(xiàn)短路情況嗎,我該怎么解決呢
我認(rèn)為是你的網(wǎng)格畫(huà)的太稀疏,六面體網(wǎng)格不支持材料的變化,就是一個(gè)網(wǎng)格只能有一種材料,按照cst默認(rèn)的網(wǎng)格設(shè)置是那個(gè)參數(shù)都為10,你要根據(jù)你的模型尺寸,調(diào)整網(wǎng)格劃分尺寸,否則失真很大
我覺(jué)得還是顯示問(wèn)題,因?yàn)榧t色的點(diǎn)是fixpoints,網(wǎng)格線是一定要通過(guò)的
六面體網(wǎng)格每個(gè)網(wǎng)格內(nèi)可以包含兩種材料(TST可以是三種材料)
我這個(gè)模型總的下面有10層左右的介質(zhì),而且介質(zhì)并不是完全一樣的,那就是六面體網(wǎng)格不適用于這個(gè)嗎
而且整個(gè)模型中用到的金屬層數(shù)有三種,選取六面體網(wǎng)格是不是不怎么適合
我是看的幫助文檔里的Differences between CST surface, hexahedral and tetrahedral meshes.
CST hexahedral meshes:
In general, hexahedral meshes do not conform to material jumps; please note that this is not necessary because CST provides the Perfect Boundary Approximation® (PBA) and the Thin Sheet Technology™ (TST) in combination with hexahedral meshes.
If the CST Multilevel Subgridding Scheme™ (MSS) is used, refinement can be local with respect to all coordinate directions. Otherwise, refinement can be local with respect to one coordinate direction, i.e. in order to account for details of the model wholemesh planes will be inserted.
Hexahedral meshing is very robust even for most complex imported geometries.
Hexahedral meshes without MSS™ are highly structured and lead to very fast computations
盡量還是不要使用子網(wǎng)格技術(shù),容易引起數(shù)值不穩(wěn)定問(wèn)題。
使用local mesh就可以了。
說(shuō)了半天連網(wǎng)格參數(shù)都沒(méi)有……,也不知道模型尺寸……。
整個(gè)東西的尺寸在450um*450um左右,像這兩個(gè)金屬條之間的間隔,也就是紫色部分是3um,綠色金屬條是10um的寬度,網(wǎng)格劃分我不記得這張圖是多少的了,
