  In the S-ALE fluid-solid coupling calculation scenario, is it possible to restart the calculation from the previous condition? How can I do it?

  Hello User,
  Yes, it seems to be possible to restart an S-ALE fluid-solid coupling calculation in LS-DYNA from a previous condition. I don't see any limitation or remark under restart section of the manual. LS-DYNA provides three types of restarts: simple restart, small restart, and full restart. Both simple and small restart functionalities are applicable to S-ALE fluid-solid coupling scenarios, as they are general features of LS-DYNA analyses, including those involving ALE/S-ALE methods.
  More details are found here: 3.8. Restarting an LS-DYNA Analysis

  Let us know how this goes.
