Detailed Description

Abstract base class for 2-D grid-based pressure solver.

This class represents a 2-D grid-based pressure solver interface which can be used as a sub-step of GridFluidSolver2. Inheriting classes must implement the core GridPressureSolver2::Solve function as well as the helper function GridPressureSolver2::SuggestedBoundaryConditionSolver.

pure virtual

Solves the pressure term and apply it to the velocity field.

This function takes input velocity field and outputs pressure-applied velocity field. It also accepts extra arguments such as boundarySDF and fluidSDF that represent signed-distance representation of the boundary and fluid area. The negative region of boundarySDF means it is occupied by solid object. Also, the positive / negative area of the fluidSDF means it is occupied by fluid / atmosphere. If not specified, constant scalar field with std::numeric_limits<double>::max() will be used for boundarySDF meaning that no boundary at all. Similarly, a constant field with -std::numeric_limits<double>::max() will be used for fluidSDF which means it's fully occupied with fluid without any atmosphere.

Parameters

[in]	input	The input velocity field.
[in]	timeIntervalInSeconds	The time interval for the sim.
[in,out]	output	The output velocity field.
[in]	boundarySDF	The SDF of the boundary.
[in]	boundaryVelocity	The velocity of the boundary.
[in]	fluidSDF	The SDF of the fluid/atmosphere.
[in]	useCompressed	True if it uses compressed system.

Implemented in CubbyFlow::GridFractionalSinglePhasePressureSolver3, and CubbyFlow::GridSinglePhasePressureSolver3.
