Rahul R 316 Report post Posted May 16 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. Quote Share this post Link to post Share on other sites

Rahul R 316 Report post Posted May 20 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. Quote Share this post Link to post Share on other sites

Rahul R 316 Report post Posted May 25 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. Quote Share this post Link to post Share on other sites

MNGFRend.out 11.84 kB · 2 downloads MNGFRend.stat 8.81 kB · 0 downloads 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). Quote Share this post Link to post Share on other sites
