Detailed Description

template<bool I>
struct FreeSurfaceOps::OpRhsG< I >

Rhs for G (chemical potential residual)

Parameters

field_name	Name of the field associated with the operator
h_ptr	Pointer to the free surface height vector (H)
grad_h_ptr	Pointer to the free surface height gradient matrix (∇H)
g_ptr	Pointer to the chemical potential vector (G)

Returns

MoFEMErrorCode

Implements Lovric 3.1d (excpet for wetting boundary term - see OpWettingAngleRhs/Lhs): R_g = ∫_Ω s(g - f(h)) - ∇s·(ε²∇h) dΩ

The template boolean I selects initialization (I=true) vs evolution (I=false).
