ABAQUS可以从隐式计算结果到显示计算进行分析,,该问题在求解一些问题是非常有用的,例如薄钢的锻造过程(经历预加载,成形和回弹),该分析预加载可以通过std分析,锻造过程可以通过XPT进行分析,最后回弹可以再用std进行分析。
ABAQUS也提供了从隐式分析到隐式分析和从显示分析到显示分析,例如可以先对感兴趣的局部构件进行分析,分析完成后,在对整个结构作分析,前部的分析结果可以传到后面的整体分析中。

保存分析结果
重启动文件包含了之前分析的信息,关于重启动的描述参阅“Writingrestartfiles”in“Restartingananalysis,”Section9.1.1;
下面做简要介绍,默认情况下,std不保存重启动文件,xpt在每个分析部开始和结束步保存重启动文件。
Std结果保存
如果想从std分析后获得结果,原始的std分析必须保留重启文件(.res),分析数据(.mdland.stt),PART(.prt),和输出数据(.odb)文件,用户可以指定具体的重启位置,重启信息除了在请求的位置输出外在每一分析步的最后也将输出。

OutputRestartRequests:
enternintheFrequencycolumnforeachstep
Xpt结果保存
如果想要从某一时刻输入xpt分析的结果,则必须在原始的结果文件中保存.abq状态文件,状态文件重启文件数据文件,PART文件和结果文件共同用来从xpt分析后的结果作为输入。
可以具体指定是否精确的时间输出xpt重启文件,因为xpt会在每个分析步的最后给出重启文件。
