三萬(wàn)、五萬(wàn)網(wǎng)格數(shù)量都成功（但是會(huì)提前完成計(jì)算未達(dá)到規(guī)定位移或計(jì)算時(shí)長(zhǎng)），加密成11萬(wàn)就報(bào)錯(cuò)
同意樓上，error說(shuō)明了有可能是材料屬性定義錯(cuò)誤，或者初始邊界條件有問(wèn)題。建議首先檢查一下材料屬性，然后再著重看下報(bào)錯(cuò)的那幾個(gè)單元的邊界條件是否有問(wèn)題。如果邊界比較復(fù)雜，你加密的話，正好有可能出現(xiàn)奇怪的東西。最后，你的mass scaling factor設(shè)置成100， 有時(shí)候也會(huì)有問(wèn)題。你可以再試試不用mass scaling.
