OptiGrid automatically detects CAD features from the grid file and displays the grid and its different edges. Edges are lines separating two or more CAD surfaces, which are automatically detected from:
BAR elements and boundary condition patches;
The topology: sharp corners, geometric features.
OptiGrid offers different options to automatically detect, add and filter edges from a mesh topology. In many cases, the default parameters are sufficient to generate an accurate CAD.
If the mesh provides no, or only partial edge definitions, the accuracy of the automatic edge detection becomes limited. It may generate a good CAD for simple meshes, but may not be accurate for meshes with irregular curvatures. In this case, manual edition of the edges may be required.
