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 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..
