HFSS網(wǎng)格劃分問題請(qǐng)教

請(qǐng)教各位大俠網(wǎng)格劃分問題：附件是我做的金納米球殼的仿真，分析的時(shí)候總是出現(xiàn)這樣的錯(cuò)誤
[error] Mesh generation has failed. Specific details may be found in 3D Modeler>Model Analysis>Show Analysis Dialog>Last Simulation Mesh.
[error] Simulation completed with execution error on server: Local Machine.
按照出錯(cuò)匯總那里的解決方法改了很多次，還一直是這個(gè)錯(cuò)誤，模型很簡單，尺寸是實(shí)物尺寸不能再改了。請(qǐng)大俠們幫我看一下網(wǎng)格劃分應(yīng)該怎樣設(shè)置。謝謝！

自己頂，大俠幫幫忙?。?/p>
