Import problem from Hypermesh and LS DYNA

Hello all,

I have been using hypermesh to mesh some parts made out of carbon composites for my car model. However i am experiencing som eproblems lately. when i try to export the model to ls prepost, it just exports nodes but the elemnts remain unexported. I am using Hypermesh 2017.1 version and LS Dyna keyword971 8.0. Could someone guide me asto what can be done to fix this problem? thanks very much in advance
