看到有很多人在问，Abaqus静态分析的结果怎样导入到fatigue中，回答如下：
是Aba的帮助的内容，也就不翻译了，反正大家都看得懂的说
将*.odb转换成*.op2格式

The translator converts certain results from an Abaqus output database (.odb) file to the NASTRAN Output2 file format.

Using the translator



Results from an Abaqus analysis are written to the Abaqus output database by using the *OUTPUT option. The following options should be included in the Abaqus input file to ensure that the results to be translated are available in the Abaqus output database:*OUTPUT, FIELD*NODE OUTPUTU,RF,CF,*ELEMENT OUTPUTS,E,SF,NFORC,Results in the Abaqus output database other than those specified above are skipped during translation. Only results from spring elements and three-dimensional continuum, shell, membrane, beam, and truss elements are translated.
For shell elements, the translator treats stresses and strains at the lowest numbered section point as being at the bottom surface and stresses and strains at the highest numbered section point as being at the top surface. Midsurface stresses and strains translated to the Output2 file are computed as the averages of the stresses and strains at the bottom and top surfaces.
Nodal results are always in global coordinates. Element tensor results are in the Abaqus element coordinate system.
Model data from the output database (nodal coordinates, element topology, material properties, and element properties) are written to the Output2 file when applicable records exist.


Command summary

abaqus toOutput2	job=job-name
	[odb=odb-name] [step=step-number] [increment=increment-number] [slim] [quad4corner]

Command line options

job This option specifies the name of the NASTRAN Output2 file to be created by the translator. It is also the default name for the Abaqus output database.



odb This option specifies the name of the Abaqus output database if it is different from job-name.



step This option specifies the step number of the Abaqus output database for the translator to translate. If the specified step contains multiple load cases, all of the load cases are translated. The default value is the last step of the analysis.



increment This option is valid only when used in conjunction with the step option. It is used to specify the increment number of the step in the Abaqus output database for the translator to translate. The default value is the last increment of the specified step.



slim This option is used to include data blocks required for postprocessing in the SLIM/VISION software (available from Third Millennium Productions, Inc.) in the Output2 file.



quad4corner This option is used to request shell output at corner nodes instead of at the centroid. This option is relevant for stress, strain, and section force output.

直接生成fil文件更省劲

对于楼主的方法是可以做，但是应力却变为原来的接近一半！，二楼的是怎么做的利用Pre&Post模块吗？还是别的方法？请赐教！

请问各位，用Abaqus\Explicit求解器求解的动力学结果文件，怎么输出fil文件，帮助文档说输出的是sel格式文件，而OUTPUT2文件只支持Standard和Frequency下的job！请求各位的帮助！！！

看过，值得讨论！
