How to Output Force vector to a result file (i.e. *.force)

Hi!!

I want to out put displacement vector and force vector to a separate result file. To do so I am using OUTPUT,ASCII,FL in *.fem file (see attachments for input file) .

Using this keywords I am able to print *.disp result file but not *.force result file (see attachments for files I am able to get).

Any leads would be appreciated.

Thanks.
