Detailed Description

Abstract base class for 3-D grid-based pressure solver.

This class represents a 3-D grid-based pressure solver interface which can be used as a sub-step of GridFluidSolver3. Inheriting classes must implement the core GridPressureSolver3::solve function as well as the helper function GridPressureSolver3::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 kMaxD will be used for boundarySdf meaning that no boundary at all. Similarly, a constant field with -kMaxD 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]	fluidSdf	The SDF of the fluid/atmosphere.
[in]	useCompressed	True if it uses compressed system.

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

◆ suggestedBoundaryConditionSolver()

pure virtual

Returns the best boundary condition solver for this solver.

This function returns the best boundary condition solver that works well with this pressure solver. Depending on the pressure solver implementation, different boundary condition solver might be used.
