Detailed Description
template<typename scalar_t>
class fdl::MACBase< scalar_t >
MAC grid a la Bridson "FSCG" section 2.4.
The "lattice coordinate" indexing of all quantities (cells, pressure, velocity components) is 1-based, i.e., (1,1,1) indexes the cell at the origin.
Definition at line 44 of file macbase.hpp.
Constructor & Destructor Documentation
| fdl::MACBase< scalar_t >::MACBase | ( | TiXmlNode * | node | ) |
Constructor using XML data.
The XML node should have tags in the following format.
<MACGrid>
<Dimensions x="50" y="50" z="50">
<CellWidth> 0.1 </CellWidth>
<InterpMethod> 0 </InterpMethod>
<Drawable>
<Velocity draw="true" r="0.0" g="1.0" b="0.0">
<Solid etc. />
<Pressure etc. />
</Drawable>
</MACGrid>
All entities in the Drawable field are turned off by default. Turning them on is accomplished by including the "draw" attribute in the tag, and setting their RGB colors.

Member Function Documentation
| void fdl::MACBase< scalar_t >::interpField | ( | unsigned | npts, |
| const scalar_t | X[], | ||
| scalar_t | uvec[] | ||
| ) |
Computes velocity field at contiguous vector of points in 3-space.
- Parameters:
-
x contiguous array of coordinates (size 3*nptsfor ODE stepper.
- Returns:
- uvec corresponding velocity vectors for ODE stepper.

| scalar_t fdl::MACBase< scalar_t >::interpP | ( | const scalar_t | X[] | ) |
Any point x that lies off the grid will be "interpolated" by the as the pressure in the closest lying cell.
Definition at line 326 of file macbase.hpp.
| scalar_t fdl::MACBase< scalar_t >::interpU | ( | const scalar_t | X[] | ) |
Any point x that lies off the grid will be reinterpreted as the center of the closest lying cell before interpolation.
Definition at line 377 of file macbase.hpp.
| scalar_t fdl::MACBase< scalar_t >::interpV | ( | const scalar_t | X[] | ) |
Any point x that lies off the grid will be reinterpreted as the center of the closest lying cell before interpolation.
Definition at line 414 of file macbase.hpp.
| scalar_t fdl::MACBase< scalar_t >::interpW | ( | const scalar_t | X[] | ) |
Any point x that lies off the grid will be reinterpreted as the center of the closest lying cell before interpolation.
