求助：patran后处理时无法进行

我参照《 MSC.Dytran Workshop Examples》上的例子进行练习，在patran进行前处理，再用dytran求解，求解之前，书中给出这样一个提示：

“ Step 24. Simulation on UNIX-platforms
Simulation on UNIX-platforms
The Dytran input deck will be named tapered_beam.dat which will be in your directory.
To run the job on Unix Platform, type in the following command in your working directory: dytran jid=tapered_beam"

请问“ dytran jid=tapered_beam”是什么意思？这一步如何操作？

我用windows系统下的dytrran进行处理，得到了结果文件，再用patran进行后处理，执行以下操作：
“
Step 26. Analysis: Read Archive File / Results / Translate
Read in the results by translating the ARCfile where the analysis results are stored

a. Analysis: Read Archive File / Results/ Translate.
b. Click Select Archive File.
c. Select and Add both TAPERED_BEAM_BEAM_0.ARC and TAPERED_BEAM_PLATE_0.ARC
d. Click Add.
e. Click Apply.
f. Click Apply.

”

在执行第f步时，给出提示
“ Message：Question from application MSC.Dytran
It is highly recommended to use the Attach option.Do you want to continue?”

如果继续执行，则会给出提示“ Acknowledgement requested from application DYTRANP3--Error Seeking in File.”

请问是什么原因造成的？
