LAX [DAMPING] [EXPLICIT dmp1] [IMPLICIT dmp2] [zone_selector] |
This keyword may be used to specify scalar dissipation parameters for the explicit differencing scheme for unstructured grids. The value dmp1 is the flux dissipation parameter, and dmp2 is the Jacobian dissipation parameter. The flux dissipation parameter only applies to the Lax (Rusanov) scheme, while the Jacobian dissipation parameter applies to all three schemes (i.e., Rusanov, Roe, and HLLE).
The default values are 0.25 and 1.5, respectively.
