=== The Linear Wireframe Mesh Generator ===
Â
You can analyze metallic wire structures very accurately with utmost computational efficiency using [[EM.Libera]]'s Wire MoM simulator. When you structure contains at least one PEC line, polyline or any curve CAD object, [[EM.Libera]] will automatically invoke its linear wireframe mesh generator. This mesh generator subdivides straight lines and linear segments of polyline objects into or linear elements according to the specified mesh density. It also polygonizes rounded [[Curve Objects|curve objects]] into polylines with side lengths that are determined by the specified mesh density. Note that polygonizing operation is temporary and solely for he purpose of mesh generation. As for surface and solid CAD objects, a wireframe mesh of these objects is created which consists of a large number of interconnected linear (wire) elements.
Â
{{Note| The linear wireframe mesh generator discretizes rounded curves temporarily using [[CubeCAD]]'s Polygonize tool. It also discretizes surface and solid CAD objects temporarily using [[CubeCAD]]'s Polymesh tool.}}
