◆ ConstructWaveTank()

std::shared_ptr< ChBody > chrono::fsi::sph::ChFsiProblemWavetank::ConstructWaveTank	(	WavemakerType	type,
		const ChVector3d &	pos,
		const ChVector3d &	box_size,
		double	depth,
		std::shared_ptr< ChFunction >	actuation
	)

Add a wave tank with a rigid-body wavemaker (piston-type or flap-type).

Parameters

type	wave generator type
pos	reference position
box_size	box dimensions
depth	fluid depth
actuation	actuation function

◆ SetLateralPeriodicBC()

void chrono::fsi::sph::ChFsiProblemWavetank::SetLateralPeriodicBC ( bool periodic_BC )

inline

Use periodic boundary conditions in lateral direction (default: false).

If not set, side boundary conditions are enforced by constructing lateral walls.

◆ SetProfile()

void chrono::fsi::sph::ChFsiProblemWavetank::SetProfile	(	std::shared_ptr< Profile >	profile,
		bool	end_wall
	)

Set the callback for the bottom tank profile and indicate if an end-wall is constructed.

By default, a tank with flat bottom and with end-wall is constructed
