Hello,
While trying to open my STL file in paraview, I am receiving errors as below. I have made my stl combing other stl files using cat stl/* > myRegionSTL.stl. All other stl files are opening successfully but this combined file named as myRegionSTL.stl is creating issues. Please help. Thanks and Regards.

The reported error is quite informative here (at line 1: Parse error. Expecting ‘solid’ found ‘-1’).
Could you please show the first lines of your combined file?

If -1 is the content of the first line of your file then there is something wrong with it.
