Hi,

I have a mesh file generate by triangle, so I have files of the type:  
.ele  
.node  
.neigh  
.edge  
.poly

Is it possible to read this mesh in freefem? How?

It is not difficult to build a code to read this kind of file  
You can use python and awk to build a file .msh (freefem for file)  
from .ele and .node file or with a good editor.
