【答案】應(yīng)助回帖

感謝參與，應(yīng)助指數(shù) +1

初步看了一下你的命令流，先說一個(gè)問題：  NSUBST 設(shè)置不對(duì)，如：
NSUBST,0.1,0.01,0.01
  其中的數(shù)值應(yīng)該是計(jì)算的子步數(shù)，必須是正整數(shù)。具體請(qǐng)見幫助文件中的有關(guān)內(nèi)容。
  對(duì)于不收斂的情況，首先可以考慮增加子步數(shù)，比如改為：
NSUBST,10,10000,2
  或者設(shè)置的更多一些。
  如果仍解決不了，且愿意支付少量費(fèi)用的話，可以通過郵件和我聯(lián)系：  htbbzzg@163.com
