Could you just add PARAM,LGDISP,1 and run again.It seems this was fixed in the version(2018.0.1) which you are currently using.

Defined PARAM, LGDISP, 1

but getting same error.

Please find attached output file.

M-NG-FR-end.out

Could you also add PARAM, KGRGD, YES as per the warning mentioned in the .out file. If it gives an error, then please share .out and .stat file.

getting same error again.

M-NG-FR-end.out M-NG-FR-end.stat

[Rahul R 328]

Please remove special character (- _ . % etc)used in part name/file name/user name & also change the run folder.Run again and let us know the outcome.

not yet solved.

 

Please find attached output file and stat file.

 

MNGFRend.out MNGFRend.stat

[Rahul R 328]

Can you give a final try by unchecking output request or param cards defined.In the past we have seen this programming error is mainly observed because of output request /param.

[narasimhamurthy 0]

removed all PARAM and output request.

 

but error not yet solved.

Last shared files are based on 2017.2.So I am commenting based on the files shared in this quote using 2018.0.1

 

This is related to some IO issue during a matrix vector multiplication in Lanczos. I am afraid I will need the model to see what could be the problem but as a workaround you could try using MUMPS as the lanczos solver via the solvtype card and see if it works out. Alternatively you could try ddm mode (even with 1 proc).
