**Viscous Layers** and **Viscous Layers 2D** additional
hypotheses can be used by several 3D algorithms, for example
Hexahedron(i,j,k), or 2D algorithms, for example Triangle
-(MEFISTO), correspondingly. These hypotheses allow creation of layers
+(NETGEN_2D), correspondingly. These hypotheses allow creation of layers
of highly stretched elements, prisms in 3D and quadrilaterals in 2D,
near mesh boundary, which is beneficial for high quality viscous
computations.
