Dear Pavlo, isn't the syntax "Output Monitor ... " and "Output Monitor_2 ... ", one being used for iteration monitors and the other for step monitors? Please see the ATENA Input Manual for details.

Regards.

Dear Dobromil,
I have tried this and haven't succeeded.
My inp file MONITOR_EXTRACT.inp:

RESTORE FROM
OUTPUT MONITOR_10 NAME "deflection" EACH STEP 
LOCATION NODES 
Node FROM 7445 TO 7445 BY 1 
Node FROM 23996 TO 23996 BY 1 
Node FROM 25510 TO 25510 BY 1 
DATA LIST "DISPLACEMENTS" END 
ITEM FROM 3 TO 3 
RECORD 
OUTPUT SUPLEMENT FROM 28 ARCHIVES 
"C:\Users\postrovskiy\Desktop\FT\ATENA\FT4_v15-test.gid\AtenaCalculation\FT4_v15-test.0002" 
"C:\Users\postrovskiy\Desktop\FT\ATENA\FT4_v15-test.gid\AtenaCalculation\FT4_v15-test.0003" 
...
"C:\Users\postrovskiy\Desktop\FT\ATENA\FT4_v15-test.gid\AtenaCalculation\FT4_v15-test.0053" 

run_inp_in_AtenaConsole.bat is located in the same folder with results and INP file:

cd AtenaCalculation

cmd /K start /B "ATENA calculation" %AtenaConsole64% /M CCStructures /execute /catch_fp_instructs /o "MONITOR_EXTRACT.inp" "MONITOR_EXTRACT.out" "MONITOR_EXTRACT.msg" "MONITOR_EXTRACT.err" /num_unused_threads=0  /num_iters_per_thread=0

 
I get the following error message:

(Thread 1) CCInpFExc: Syntax error reading ATENA input, line: 2, file: MONITOR_EXTRACT.inp, data being processed:

Dear Pavlo, yes, an empty .inp with just RESTORE and the monitor definition + results file update commands.

Dear Dobromil, thank you for prompt replies! I'd like to clarify some points.

Should I create an empty .inp file or add this into .inp file created by GiD?
Should I put my code right after "RESTORE FROM" command?

This code was generated automatically by Monitor request procedure. I have just tested it, it works.

It was mistype, of course there should be a space.

OK, it seems that it can be easily done directly from Atena Studio.

Dear Pavlo,
I. for manually executing .inp file commands, I recommend creating a .inp and running it in AtenaConsole. Just add a RESTORE FROM command at the beginning to read the results from the last step (or more precisely, the one you have active in postprocessor when preparing the command) at the beginning of the new .inp file.
Close ATENA Studio, run the .inp, then open ATENA Studio postprocessor again.

II. I doubt combining multiple quantities in a single monitor ("BOND_SLIP" "STRAIN" "STRESS") makes sense / is supported at all...

III. I doubt "Node FROM 19436 TO 19436BY 1" can work without a space before "BY".

Ad 2.: The LC coeffs monitors are automatically generated and show the summed-up multiplier corresponding to each load case. If this disturbs you, you can try to comment-out (or delete) the definitions of "LOAD_CASES_CONTRIBUTION" monitors before the 1st load step, looking like:

OUTPUT  MONITOR_2 NAME "% of load in interval" EACH STEP
LOCATION OUTPUT_DATA
DATA LIST "LOAD_CASES_CONTRIBUTION" ITEM FROM 2 TO 2 END
TRACK ;

OUTPUT  MONITOR_2 NAME "summation % of load in interval" SUMMATION EACH STEP 
LOCATION OUTPUT_DATA
DATA LIST "LOAD_CASES_CONTRIBUTION" ITEM FROM 2 TO 2 END
TRACK ;
