  How to write the /NERR command in ansys workbench? I tried different options obtained from google but it is not working. Where I have to write the command, in solution part ? or at any other region in tree? I tried
  
  /NERR,,,-1
  
  but not working
  
  also I tried /NERR,,999999,
  
  but not working
  
  Please help me

  The /Nerr command can be written in /PREP7 or /SOLU. What exactly is the issue and what do you mean it is not working?
  
  It is important to use the Ansys help rather than relying on google for such things.
  
  I often use /NERR,,99999999
  
  Using this when solving allows up to that many warnings before aborting the solve. That number is the maximum integer it can take.
  
  The /NERR,,,-1 will not work as the third field is unused. Also no other field accepts negative integers other than the first (NMERR).

  it is nor working means: the solver stops and giving a message like this
  
  ************************************************************************
  The number of ERROR and WARNING messages exceeds 10000.
  Use the /NERR command to increase the number of messages.
  The ANSYS run is terminated by this error.
  ************************************************************************
  
  how and where can I use the NERR command to rectify this issue?

  use the command I have listed above. Use a command object in the analysis folder, the same tree location as loads and boundary conditions.
  
  /NERR,,99999999
  
  that is eight nines.
  
  If you are doing a resumed analysis (buckling, MSUP...) you may need to insert the command object under analysis settings. Right click on analysis settings and insert command object.
  
  also check your .err file for any warning or error messages that may specifically be causing issues.

  I think I have inserted the command as you told. But still the problem persist : (
  
  the first command is the inistate command and the second one is the /NERR command

  Then there must be an error occuring. Right click on your Solution (B6) tree object and open solver files directory. look for the .err file and check for any errors.
  
  If you can't find the error, archive your project without results and post it here. I will take a look and let you know if I find anything.

  i wrote the /NERR command in the same command file of inistate comand. now the solver is running. i dont know what will happen. I will inform you. Thank you for your consideration and timely reply

  I think when I wrote the command first it worked for warnings. but the error message I obtained are the following. How can I rectify the issue?
  
  Element shape checking is currently inactive. Issue SHPP,ON or
  
  SHPP,WARN to reactivate, if desired.

  You are obviously doing a non linear solve. The solution has failed to converge.
  
  I would recommend doing some research, looking at the results at time 1.52 to see where convergence may be having trouble. Then prepare details of your analysis, what you are trying to solve? what are the non-linearities in the model? etc... and then starting a new discussion with more specifics.
