預(yù)應(yīng)力求解問(wèn)題

問(wèn)題是這樣的，我現(xiàn)在要做激光器封裝應(yīng)力應(yīng)變分析，先進(jìn)行回流，在回流求的形變和應(yīng)力的基礎(chǔ)上在求解激光器工作時(shí)候的應(yīng)力和應(yīng)變。單獨(dú)進(jìn)行回流和單獨(dú)進(jìn)行工作的都做過(guò)，都沒(méi)問(wèn)，但是現(xiàn)在整合到一塊就各種報(bào)錯(cuò)，現(xiàn)在有一個(gè)問(wèn)題，程序跑不下去了，錯(cuò)誤日志的提示是這樣： *** ERROR *** CP = 143.209 TIME= 21:08:24 The size of the displacement vector in the .ESAV file is 27914. It does not match with the size of the displacement vector in the current analysis which is equal to 83742. Please send the data leading to this operation to your technical support provider, as this will allow ANSYS, Inc to improve the program. *** ERROR *** CP = 143.677 TIME= 21:08:58 File file.mode does not exist. 我的命令流是這樣的，建模和網(wǎng)格就不放了，因?yàn)槟Ｐ褪亲詈?jiǎn)化的用來(lái)測(cè)試求解代碼能不能運(yùn)行的，所以網(wǎng)格很粗陋，錯(cuò)誤很多（已經(jīng)2000多K了錯(cuò)誤日志），不過(guò)我覺(jué)得應(yīng)該不影響后面求解命令的執(zhí)行。求解命令： *** ERROR *** CP = 143.209 TIME= 21:08:24 The size of the displacement vector in the .ESAV file is 27914.
