Isogeometric analysis

      Hello Team,

      This is Nikhil Khaire, currently, I am exploring the Iso geometric analysis (IGA) capabilities available in the LS prepost.

      For the initial stage, I have started with the 3pt bend analysis. The 2- hollow rectangular (see Fig1)beam was used for test case.  With available capabilities in the ls prepost, I have created the set up. However, I am facing issue with Connection at the T- joint.

      While creating the mesh I used the build contact option which generates the Contact ( Nurbs tied_edge to edge) and also generate the IGA keyword Tied edge to edge (see  fig.2).

      The followings problem I am facing while running it.

      1. when I launched the job the, it get error out with message “ The Nurbs tied_edge to edge is not a valid Keyword)

      2. I removed the keywords from the file and re run and job completed with normal termination. However, at the start there was a  warning (see fig.3)

      3. When I checked the simulation results there was no connection of the middle wall (see Fig 4)

      I used smp_s_R13_0. SOLVER to launch the run.

       

       

      Please kindly provide any suggestion to resolve this issue.
