7.14.1.19. Sp

Beta Capability

The spherical harmonics capability is not well tested and should be used with caution.

Syntax

Eq Sp Order for Associated DoF [{of} SpeciesName | {in} MaterialPhaseName | {ls} {a | b | c}] {on} MeshPart using Interp with {Term_0} … {Term_N}

Scope

Aria Region

Summary

Specifies the Spherical Harmonics equation set to solve for Participating Media Radiation (PMR). User provides the order, degree of freedom associated with the equation, the element type and the mesh part (element block) on which to apply the equation (see SPn Radiation).

Description

Admissible values for Order are odd values (1, 3, 5, …).

The only admissible value for Dof is ANGULAR_INTENSITY.

Admissible values of Interp are Q_{1}, Q_{2}, Q_{2S}.

The only admissible value for Term_n is SRC.

The Meshpart must be an active element block.
