GENERATING THE MESH

Now that the model is finished, it is ready to be meshed. The mesh will be generated using Chordal Error in order to achieve greater accuracy in the discretization of the geometry. The chordal error is the distance between the element generated by the meshing process and the real profile of the model. By selecting a sufficiently small chordal error, the elements will be smaller in the zones with greater curvature.

Generating the mesh using Chordal Error

NOTE : By default GiD corrects element size depending on the form of the entity to mesh. This correction option may be deactivated or reactivated in the Meshing card in the Preferences window under the option Automatic correct sizes .
