Coupled Transient Thermal Analysis with LS-Dyna Structural Simulation

  Hello,
  I am trying to simulate the excitation of a laser pulse on the surface of a slab. I have performed my thermal transient analysis (see picture below) and I want to couple the results with LS-dyna (The reason that I am using LS-Dyna is because I want to use the non reflecting boundaries that only LS-dyna offers in order to avoid the elastic wave reflections therefore reducing the simulation domain). I am using ANSYS 2024 R1 but It seems I cannot import the heat flux results to LS-Dyna Workbench in order to perform the structural part there. Has anyone else performed something similar?
  thank you for all your help and support

  Hi Emmanouil,
  I haven't done the specific application you're referring to but using 2024R1 I just created a generic model in Transient Analysis, and then imported the model along with the resulting heat flux to LS-DYNA and performed a structural analysis. Could you check in your model if the two analysis systems are properly linked in the Workbench as shown in the screenshot below?
