Question

ABAQUS在看形变结果时出现The selected primary variable is not available in the current step/frame.

Answer 1

我也遇到了此类问题，后来我发现是由于出现了云图所对应的状态变量计算得到无穷的计算结果，后来我修改了形式就OK了

Answer 2

If after applying all above still you face the same error, then I suspect it's a computational issue rather than a programming issue e.g. the stress or strain values returned from your UMAT code are infinite.
Therefore, I suggest for a simplified model, test your subroutine and for example check the returned stress values from your UMAT code. You may do it using the command "Print" or "write" through your subroutine. In case you don't know how, for example somewhere in your subroutine put:
write(*,*)'UMAT is called'
print,'STRESS1=', stress(1)
Do the same for any parameter you have defined in your UMAT code and check if their values are normal (not infinite). If you see any infinite value, surely that would be one of the reasons that your OUTPUT cannot be displayed and you have to modify your calculations. The above-mentioned values (e.g. STRESS1) are normally written in the *.log file.

Answer 3

修改工作目录, 计算完成后在工作目录下重新打开ODB文件就可以了
或者直接在默认工作目录下寻找odb文件, 打开

Answer 4

会不会是你在STEP中的场输出中没有设置你要的结果啊

Answer 5

关键字设置有问题
