TAGGED: 2D, ale, ls-dyna, structured-mesh
March 8, 2023 at 9:09 amlm32Subscriber
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.

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.

Please get today's version from our "beta" dir.

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
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?
