Hi everyone

I ran a LIGGGHTS DEM code and want to see results on Paraview; However I get the following error  
**CFDEM-PUBLIC-5.x/run/out0.stl at line 3: unable to read STL vertex.**  
The following attachment is the output stl file  
[out.stl](https://discourse.paraview.org/uploads/short-url/oSZs14fB0Bflf2uDODBjFKudHvH.stl) (1016.1 KB)

I`d be grateful if you can help.  
Regards

This is not a STL file but a LIGGGHTS data file.
