    Hi @LKZ

     

    Please addd NLOUT with SVNONCNV set to YES and provide a value.

     

    With this, even if the run fails, non-convergent results will be written to .h3d.

    @Prakash Pagadala I have found the NLMON can do this.

     

    But it just can output deformation (written in help).

     

    If today I wan the file written with the contact force or pretension.

     

    Does Optistruct can do this?

    Hi @LKZ

     

    NLOUT will write to H3d and all timesteps are a part of h3d. 

     

    NLMON will write a .nl.h3d which is used for monitoring non-linear analysis. So the results or deformation at any increment may not be acceptable as iterations go back and forth

    Because I just want to see the full model contact successfully at first.

     

    Then the analysis will make sense at later time step.

     

    So here suggest to open the NLMON to see the contact situation then it can continue to analysis, is that right?
