Student Version: How can I export the mesh to LS Dyna Prepost/L Dyna for post-processing?

I am a graduate student doing research. I wish to use HyperMesh to mesh some of my models, but the I wish to export the mesh for post-processing in LS Dyna. I am aware there is an option to do that, however it seems that it is not showing in the student version. I have looked into exporting the file as Nastran format however I could not find the option to export it like that either. The only three options showing are: OpiStruct, RADIOSS and Feko. Could someone please help me this?

Thank you for your time.
