How to delete the edges or lines on the surface when I import a .stl file

Hi all,

 

I am using Hypermesh of version 2017.2 to process a geometry.

We used Meshmixer to generate a surface geometry and export as the .stl file. However, the Hypermesh just regards .stl file as mesh when importing the file to it. And it looks like this after import:

I want to convert it into geometry first. So this is what I do:

Geometry > creat > surface > from FE

This is the setting of from FE:

The surface looks like this:

My questions are

1 What the points are on the surface? They are made by Hypermesh? 

2 How to delete the edges on the surface? Because I need to assemble this geometry with another later, and the edges are redundant and a big problem for me to mesh in the future. And I have imported the .stl file into Comsol, and it regards the surface as a whole without edge. So I think the edges might be the features recognized by Hypermesh.

 

Thanks a lot!
