TSL | THIN SHEAR LAYER - Thin shear layer option

Structured Grids

{TSL | THIN} [SHEAR] [LAYER] word1 word2 word3 [zone_selector]

[Note - This keyword is considered obsolete, and may be removed in the future. The same capability is available using the RHS VISCOUS keyword.]

For structured grids, this keyword turns off the viscous terms in specified coordinate directions. The parameters word1, word2, and word3 are keywords controlling the viscous terms in the ξ-, η-, and ζ-directions, respectively. They may have the following values:

	Keyword		Meaning
	`VISCOUS`		Retain all viscous terms in this direction
	`INVISCID`		Neglect all viscous terms in this direction

By default, when INVISCID is set for a direction, the scalar implicit operator will be used in that direction (the full block implicit operator is used in viscous directions). This may be overridden using the IMPLICIT keyword.
