Looking for help – 2D structured ALE

  Hello everyone,
  I am trying to solve a 2d problem, with a structured ALE mesh interacting with a Lagrangian structure. After a certain time, the material in the ALE mesh develops a very small timestep, so I would like to delete it using TDEATH. However, when the mesh is deleted, the simulation ends with the following message:
  **** Error 40178 (SOL+178)
  Material type 0 is unavailable for
  2D plane and axisymmetric elements
  Does anyone have a suggestion what is happening? i only used material types with other numbers.
  Thanks!

  Is this using ALE or SALE? Recently a bug has been fixed in SALE that may be related to this (TDEATH). Please try with the latest beta (today's version) first.

  Hi Ido, Yes it is SALE. I am using ANSYS version 2023R1 (LS-DYNA Version R13). Which version should I try?

    Thanks for the advice, using LS-DYNA version R14 solved the bug, but unfortunately I now get the following message after TDEATH has passed:
    *** Error 40502 (SOL+502)
    node # 1303667 has out-of-range velocities
    x-velocity= NaN
    y-velocity= NaN
    
    I get this message for the nodes of the S-ALE mesh immediately after it is deleted. Is there a way to solve this for a 2D axisymmetric model?
