Detailed Description

This class reads from STL file format and creates triangular elements in given model_part.

The current version only reads triangles from the STL and not higher order polygons The nodes corresponging to given vertices are not collapsed A SubModelPart for each additional solid block will be created For definition STL format please check https://en.wikipedia.org/wiki/STL_(file_format) A sample file format with 3 triangles: solid 3 triangles facet normal 1.000000 0.000000 0.000000 outer loop vertex 0.1 -2.56114e-08 0.1 vertex 0.1 -0.499156 -0.0352136 vertex 0.1 -0.473406 -0.0446259 endloop endfacet facet normal 1.000000 -0.000000 0.000000 outer loop vertex 0.1 -0.473406 -0.0446259 vertex 0.1 -0.447464 -0.0534931 vertex 0.1 -2.56114e-08 0.1 endloop endfacet facet normal 1.000000 0.000000 0.000000 outer loop vertex 0.1 -0.6 0.1 vertex 0.1 -0.524702 -0.0252604 vertex 0.1 -0.499156 -0.0352136 endloop endfacet endsolid 3 triangles
