    stady state dynamic in LS-DYNA

    I’m trying to understand how LS-DYNA SSD Module works. For this purpose, I’m solving a simple mass-spring system from a textbook. I tried to solve it with two approaches: 1. Time-domain: The result matches very well with the book. 2. Frequency-domain (SSD): unfortunately, I could not...

    How do separate parts that share some same nodes?

    Hello everybody, I have a model with two parts. In the contact interface, the parts share some nodes. How can I separate those parts with less effort?

    remeshing the results of a simulation in hypermesh or ls prepost.

    Hello everybody, I have a mesh like a picture below. How can I change the element size or remesh the model in Hypermesh? I know that I can do it one by one. But is there any way to do it faster concerning the current mesh geometry?

    axisymetric simulation results to solid mesh - LS-Prepost or Hypermesh

    Hey guys, I want to use the results of an axisymmetry forming simulation to create a 3D mesh (revolve on symmetry axis). The 3D mesh should also contain residual stresses. I used LS-DYNA to perform the forming simulation. The residual stresses are available in dynain file. How can I create the...
