No time stepping.

Template Parameters

System	CoupledSystem.
RhsAssembler	Poisson RHS assembler.
Elliptic	elliptic backend (EllipticSolver concept, default GeometricMG).

template<class Limiter , class NumericalFlux , class Block >

void pops::SystemAssembler< System, RhsAssembler, Elliptic >::block_residual ( Block &  block, MultiFab &  state, MultiFab &  R, bool  recompute_aux  )

inline

Residual R = -div F + S of a block at a stage (with field re-solve if recompute_aux).

This is the method-of-lines arrow the Driver passes to the TimeStepper. Fills the ghosts of state per block.bc before assembly.

Here is the call graph for this function:

◆ solve_fields()

template<CoupledSystemLike System, class RhsAssembler , class Elliptic = GeometricMG>

void pops::SystemAssembler< System, RhsAssembler, Elliptic >::solve_fields ( )

inline

Solves the system RHS (Sum_s q_s n_s), the Poisson, then derives aux = (phi, grad phi).

aux() is up to date on return.
