Hi,
i am modeling a hat chaped specimen for a hopkison bar test, however i am getting excessive deformation so i think i should switch to an ALE model or Eulerian model. The problem is i don't know much about ALE modeling for solids, i started by simply choosing the ALE formulation in the material type and adding the ALE_CFD_SPH card but the results are not correct at all. What am i doing wrong? is it possible to attach the model and get your opinion on what i should do? the model i have right now is stil in lagrangian formulation wich works well until the excessive deformation starts to happen.
