I am trying to make a prestress bird strike analysis. In prestress (Static Structural) i have thermal, pressure and bolt preload loads. I am using SPH particle method to model bird, however, static structural doesn't support that. I couldn't find any way to solve it yet. Do you know how can constrain the SPH bird in static structural module? Or how can map the stresses which comes from WB Static structural to LS Dyna Explicit model ?

you can try to use the dynamic relaxation type Explicit after Ansys solution by connecting the prestress solution to the model of the lsdyna.
You can use assembly workflow and introduce the SPH bird in the second part of the analysis and define as SPH.

Thanks for your feedback. Also i have a question. I will define the part that exposes to bird strike with Johnson Cook or Cowper Symonds material cards. In the static structural is it applicable?
