ACP-Post error – …solution vector and model mismatch!

    • Marvin

      Hi,

      when I try to create stress under Solution in ACP-Post, I get an error "Post-processing evaluator: Post-processing solution vector and model mismatch!" The solution itself is being updated successfuly (judging by the green ticks)

      What exactly does that error mean, and what could cause it?

       

      Thanks.

      Marvin,


        Can you open your model and show the details? Is the error in Static Structural part or the ACP part? check the time at which you are requesting the result, is it last?

      Hi Sandeep,


      sorry for the late answer, I had hardware related problems.


      I am not sure where do I request the time of the result. I tried to change ''Store Results At'' and ''Retain Files after full Solve'' from ''No'' and ''All time Points'' to ''Yes'' and ''Last time Point''. In both cases the error is the same.


       



      The error shows up in ACP (Post).



       


      I also have some Command Snippets, that I need, maybe they are interfering in some way?



       


      Regards,

      Hi Marvin,


      From what I see in the commands, they are not affecting the result file, but can you try and suppress and run w/o them?  I realize the one that has the D commands is needed to hold the model and will affect the run, but can you put in alternate constraints via built in methods (fixed support for example).  Just as a test.  Try that and let us know.  Thank you.

      I ran the model w/o commands – the error is the same in ACP Post.

      Hi Marvin,


       


      OK, let me inquire with our development staff. This is not something we have seen recorded as an issue.  Thanks for your patience.

      Hi Marvin,


      At 17.0 we saw some minor issues, so please try these steps.


      - Perform a clear generated data on ACP Pre Setup cell
      - Update the solution on the WB project schematic
      - Refresh ACP Post
      - Launch it and update the model in ACP Post
       
      You could also try deleting and connecting back a new ACP Post.
       
      Now, if these do not work could you update to a more current version?
       
      Thank you
      Sean
