Aided Mesh
Mesh the domain quickly and easily
Requirements for automatic mesh generator:
No specific mesh information
An initial mesh respecting the geometric features
Tools Global settings for meshing
Control mesh locally – point, line, face, volume
Special tool for specific characteristics of the physics: meshing of the skin depth
