error while getting output of energy command

[ace21]

Dear FEAP users

I am using FEAP ver 8.2.

I wanted to extract the energy values, so just to test I ran a simple quasi static 3D cube example with elastic material, with the following command for energy ( as per feap manual instructions) by adding the following command before the solution increment loop

BATCh
TPLOt
END
ENERGY

however I get the following error msg

At line 91 of file ptmplt.f (unit = 30, file = 'P_teta.ene')
Fortran runtime error: Sequential READ or WRITE not allowed after EOF marker, possibly use REWIND or BACKSPACE

I tried to follow the remedy suggested by the comiler error msg, but the problem still presists

Could you kindly point out what I am doing wrong and how to possibly solve this problem

best regards and thanks in advance

8.2 is a very old version.  It could be that the coding is incompatible with modern compilers.
The feature certainly works in 8.5, maybe you should upgrade.

Another possibility is that the version you have is corrupt (has been edited incorrectly).  You could try downloading a clean version from the distribution site.
