Hypermesh常見(jiàn)錯(cuò)誤和知識(shí)集錦

1、消除不必要的細(xì)小特征：孔倒角調(diào)用多個(gè)C P U2、由點(diǎn)確定矢量方向3 RROR # 2502A fatal error has been detected during input processing:* ERROR # 2502 *Element 549700 had incorrect node numbering sequence and needs renumbering.* ERROR ENCOUNTERED BEFORE COMPLETING THE CHECK RUN *(1) 一般發(fā)生在修改網(wǎng)格之后，再刪除原來(lái)的網(wǎng)格的時(shí)候沒(méi)有將element549700刪掉，使得該單元上的節(jié)

2、點(diǎn)與后來(lái)劃分的網(wǎng)格的節(jié)點(diǎn)出現(xiàn)矛盾沖突；先利用 find id=549700 刪掉該單兀一Save found -F5-mask-retrieve(選擇保存 的)reverse( 反選)mask-只顯示549700單元了4 * ERROR # 1237 *CHEXA element number 26323 references a missing property ID 23 or uses property of incorrect type for this element type.(1)由于property ID 23(23號(hào)屬性定義有問(wèn)題)，沒(méi)有定義一個(gè)正確的單元類型；(2) 這個(gè)地

3、方容易沒(méi)有填，注意注意(3)網(wǎng)格劃分的質(zhì)量也有可能出現(xiàn)這個(gè)問(wèn)題，重新劃分網(wǎng)格可以消除該錯(cuò)誤。(網(wǎng)格畫小)5* ERROR # 2203 *Error(s) encountered during element check* Element Quality Check Failed - error limits violationNOTE : To bypass element quality checks (except essential validity checks) use PARAM,CHECKEL,NO.

9、 Case Control data SPC or SPCADD is missing in bulk data.(1)主要原因：constraint ,或者是load的定義為空，就是沒(méi)有數(shù)值；解決方法：將其他的collector 隱藏，只顯示load collector ，查找到未定義的load 就定義上就Ok 了(2) 在定義loadstep時(shí)SPC是約束，LOAD載荷，注意可能這里弄反了10創(chuàng)建節(jié)點(diǎn)集即節(jié)點(diǎn) sets11* ERROR # 192 *(1)優(yōu)化設(shè)計(jì)的topology中優(yōu)化最小尺寸定義的太小，改大一些可以解決12 * ERROR # 842 *DTPL or DSIZE c
