Using Static Structural Initial Condition for Explicit Dynamics 2D

  I want to perform an explicit analysis on a prestressed geometry (gravity body load). My analysis is in 2D and I'm not able to connect static structural and explicit dynamics modules. Is there a way how I can do it? As it is taking a very very long time to reach steady-state in explicit dynamics.

  Hi Siddharths,
  
  Prestressed explicit dynamics analysis is only available to 3D. Please refer to this page on the Ansys Online Help: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/exd_ag/exd_ag_prestress.html
  
  Alternatively, you may try giving your model a small thickness (making it 3D) and constraint the out-of-plane movement to represent a plane strain case.

  Thank you for your reply.
  
  I am performing an axisymmetric 2D analysis, it is computationally expensive to perform a revolve and make it 3D. Is there any way I can perform my 2D implicit static/transient and later combine it with explicit dynamics? Is there a way in which I can export my implicit as an input file and import it as an initial condition to my explicit analysis?
