Fluent出現(xiàn)Update-Dynamic-Mesh failed. Negative cell volume detected何解?
|
|
用fluent+mpcci+ABAQUS做高超聲速飛行器的流-固-熱仿真,用的是2D的結(jié)構(gòu)化四邊形網(wǎng)格。 1. 步長(zhǎng)設(shè)置大,報(bào)錯(cuò)the stored buffer time frame is out of the last grid time 0. Either the grid time 0 has not been received by the code or the history size is too small.Check either the "Initial quantity transfer" option or the "HistorySize" setting. 2. 步長(zhǎng)設(shè)置剛好的話,報(bào)錯(cuò)Update-Dynamic-Mesh failed. Negative cell volume detected. 3. 步長(zhǎng)設(shè)置過(guò)小的話,報(bào)錯(cuò)Job deadlock situation detected。 請(qǐng)問(wèn)步長(zhǎng)設(shè)置剛好的話,如何設(shè)置動(dòng)網(wǎng)格,防止負(fù)體積出現(xiàn)?@wuming524 |
