I have a model with glued contact..I can get ouput for stress, CBUSH/ELFORCE, displacements,etc.,et .but I can NOT get contact status to show up in PATRAN, either for H5 or .OP2..what am i doing wrong?

  • Hi Robert,
     
    Following is from SOL 101, be sure you are using param,post,1. SC0 where the contact initialization are done will contain the contact status.

  • HI Sanjay..here's my case control..I've run both Post, -1 and +1..and do get H5 output..just no Contact status.

    One thing..theres a -525 deg F temp load on the model, with CTE mismatches..things are pulling away from each other, which
    I've accounted for with contact params,,,displaced shape makes a lot of sense...
    Also including the BCTABLE..

  • Robert, You are dealing with the same issue with Edwin on the support desk. It would be best to send him the file and we can sort this out. Perhaps something specific in this model. Thanks.
  • I can..it's a big model..I'm trying some things now..I really was hoping it was something simple, especially in the BCTABLE, BCPARA cards...but apparently not
  • Sanjay..I don't want to make a big deal re: contact status..I really thought it was going to be a simple answer. I can't believe I'm the first to see this ..I'm sure you guys have seen this before.
    .IF not , then MSC developers have a problem..I get ALL results except contact status..

    I've had numerous issues over the last month with ATA/Siemens/MSC?Hexagon in terms of new version issues, and things that used to work don't work w/a new release..it's been VERY frustrating, since
    I've spent a lot of time trying to understand something hat could be broke

    BUT, for a technical question that I hope you can answer..I'm running touching and glued contact..I get this statement as part of the sol'n sequence and I
    Can't figure out what it means, since these two elements are not close together..I queried HEXAGON but can't find anything..I wish Vinay and Zhong were still around

  • My test as I indicated is working... Best thing to do here is follow up with support ticket that you have open with the files. We are here to support you with the staff we have. Please help us help you.
  • Sanjay..

    I'm going to reduce the size of the model to capture the areas that seem to be problematic (proprietary/security issues here), and send it over//probably Monday. Since
    The model is doing what I expect.. Since I'm not up to speed with all the PATRAN_related post-processing options , I'm wondering if the MDLPRM card is not setup right..

    But.......thanks for your help Sanjay. When I call the Hex support phone number, I never get a person..always have to leave a message, and a short one at that..it
    Discconnected me twice this week when I was leaving a message related to these issues
  • Sure, we will look into it. I know the phones are working since I have answered your call live likely in the last month or so. Likely support staff is on other calls/cases.. We also have queuing agents who will answer the phones and take your messages in this instance. As you know...and have done...You can always drop an email as well to support. Thanks for your continued usage of our products. We are here to help resolve the issues and difficulties you experience and improve the software with your valuable feedback.
