TAU 2D Regular Mesh Generation (Non-Rotational Models)
If the model is not identified as a rotational model, the TAU 2D regular mesher is used to generate the mesh. TAU 2D mesher does not use Parasolid union as the Classic mesher does. Instead it reads the objects individually as-is. Remesh technology is used to get the best representation of the curves with minimum mesh points.
The TAU 2D regular mesher uses a top down meshing algorithm that starts the mesh from a uniform base mesh, then adapts the mesh in the necessary regions, and does the boundary recovery later. Mesh quality is controlled and maintained during the entire meshing process. To maintain a uniform mesh, 1:2 splitting method is used for the transitions from small elements to large elements.
In most cases, users do not need to add any additional seed refinement mesh operations. The mesh can be directly used to do the transient simulation. For solvers with adaptive passes, a few passes can be saved for the convergence although the initial mesh is larger since it is high quality and uniform.
