Hello George Papazafeiropoulos
Sorry to bother you so often, but now I have a problem. MATLAB prompt warning: No results corresponding to the specified record key are written in the fil file.Do you know why?

Hi George, actually this is the original file from Getting started example Job 1.inp.
** OUTPUT REQUESTS
**
*Restart, write, frequency=0
**
** FIELD OUTPUT: F-Output-1
**
*Output, field
*Node Output
COORD
*Element Output, directions=YES
S
**
** HISTORY OUTPUT: H-Output-1
**
*Output, history, variable=PRESELECT
*End Step
I added the *FILE FORMAT, ASCII later, but it didn't work for me. There is no fil file.
