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.
