  Yes, but now you have the LS-DYNA solver installed. Go to the Start Menu and under ANSYS 2022R2 LS-DYNA Student select LS-Run. Use that to submit a .k file to the solver. Under that same folder is LS-PrePost that you can use to build a .k file of your model and look at the results.
  Good luck!

  I'm not an expert at LS-DYNA, I'm an expert at Workbench. I had a quick look in the free Ansys (Student) Workbench and in LS-PrePost and noticed that in Workbench, I can export a Nastran file and in LS-PrePost I can import a Nastran file. I often do meshing in a Modal analysis block and Export Nastran file then open that in Femap where I finish preparing the file to submit to the Nastran solver.
  On a paid Ansys Workbench license, LS-DYNA is an analysis system that you can drag into the Project Schematic, just like you can with Explicit Dynamics. This feature is not included in the Student license.
