Detailed Description

2-D single-phase pressure solver.

This class implements 2-D single-phase pressure solver. This solver encodes the boundaries like Lego blocks – if a grid cell center is inside or outside the boundaries, it is either marked as occupied or not. In addition, this class solves single-phase flow, solving the pressure for selected fluid region only and treat other area as an atmosphere region. Thus, the pressure outside the fluid will be set to a constant value and velocity field won't be altered. This solver also computes the fluid boundary in block-like manner; If a grid cell is inside or outside the fluid, it is marked as either fluid or atmosphere. Thus, this solver in general, does not compute subgrid structure.

overridevirtual

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.

Implements jet::GridPressureSolver2.
