Function Documentation

apply_pressure_gradient()

void amr_wind::overset_ops::apply_pressure_gradient	(	amrex::MultiFab &	mf_vel,
		const amrex::MultiFab &	mf_density,
		const amrex::MultiFab &	mf_gp,
		const amrex::Real	scaling_factor )

iblank_node_to_mask_vof()

void amr_wind::overset_ops::iblank_node_to_mask_vof	(	const IntField &	iblank,
		const Field &	voff,
		IntField &	maskf )

VOF-sensitive conversion of iblank to mask at nodes

Masks most of the domain, including a layer around solid bodies, but avoids masking cells near the interface

iblank_to_mask()

void amr_wind::overset_ops::iblank_to_mask	(	const IntField &	iblank,
		IntField &	maskf )

Convert iblanks to AMReX mask

\begin{align}\mathrm{mask}_{i,j,k} = \begin{cases} 1 & \mathrm{IBLANK}_{i, j, k} = 1 \\ 0 & \mathrm{IBLANK}_{i, j, k} \leq 0 \end{cases} \end{align}

prepare_mask_cell_for_mac()

void amr_wind::overset_ops::prepare_mask_cell_for_mac

(

)

VOF-sensitive conversion of iblank to mask at cells

Same concept as iblank_node_to_mask_vof, but for MAC projection

replace_gradp()

void amr_wind::overset_ops::replace_gradp	(	amrex::MultiFab &	mf_gp,
		const amrex::MultiFab &	mf_gp0,
		const amrex::iMultiFab &	mf_iblank )

revert_mask_cell_after_mac()

void amr_wind::overset_ops::revert_mask_cell_after_mac

(

FieldRepo &

repo

)

Convert iblank to mask using ordinary method

Intended to return mask_cell back to original values following prepare_mask_cell_for_mac because mask_cell is used in other parts of the flow solver, not just the MAC projection
