我在做冷流與暖流的交匯問題 中間是固體域 上面是暖流下面是冷流,固體域中間有孔,最后固體域的溫度場(chǎng)計(jì)算有錯(cuò)誤,想請(qǐng)教怎么解決
已經(jīng)設(shè)置了JC本構(gòu)和JC失效參數(shù),結(jié)果還是只能形變,不會(huì)發(fā)生材料失效


如題
A large negative pivot value (-4.185690834E-07) has been encountered in the global assembled matrix at the UZ degree of freedom of node 674122. This may be caused by a bad temperature-dependent material
