Detailed Description

Example of a gaussian density distribution plus a constant density.

Parameters: a_gamma - Gamma for polytropic, gamma-law gas a_ambientDensity - Ambient density add to the density gaussian a_deltaDensity - Mean of the gaussian a_pressure - If 0, use isentropic pressure if 1, use the constant pressure of 1.0 a_center - Center of the gaussian a_size - Standard deviation of the gaussian a_velocity - Initial velocity of the gas a_artvisc - Artificial viscosity coefficient

Member Function Documentation

void GaussianIBC::fluxBC FArrayBox   a_F,
const FArrayBox   a_W,
const FArrayBox   a_Wextrap,
const int &    a_dir,
const Side::LoHiSide   a_side,
const Real   a_time
[virtual]
 

Set boundary fluxes.

Implements PhysIBC.

void GaussianIBC::initialize LevelData< FArrayBox > &    a_U [virtual]
 

Set up initial conditions.

Implements PhysIBC.

PhysIBC* GaussianIBC::new_physIBC   [virtual]
 

Factory method - this object is its own factory.

Return a pointer to a new PhysIBC object with m_isDefined = false (i.e., its define() must be called before it is used) and m_isFortranCommonSet set to value of m_isFortranCommonset in the current (factory) object.

Implements PhysIBC.

void GaussianIBC::setBdrySlopes FArrayBox   a_dW,
const FArrayBox   a_W,
const int &    a_dir,
const Real   a_time
[virtual]
 

Set boundary slopes.

The boundary slopes in a_dW are already set to one sided difference approximations. If this function doesn't change them they will be used for the slopes at the boundaries.

Implements PhysIBC.

void GaussianIBC::setFortranCommon const Real   a_gamma,
const Real   a_ambientDensity,
const Real   a_deltaDensity,
const int &    a_pressure,
const RealVect   a_center,
const Real   a_size,
const RealVect   a_velocity,
const Real   a_artvisc
 

Sets parameters in a common block used by Fortran routines.

void GaussianIBC::setFortranCommonSet  
 

Set the flag m_isFortranCommonSet to true.

Set the flag m_isFortranCommonSet to true so that new IBCs made with new_physIBC() will have this flag set without calling setFortranCommon() (this is a clumsy design and should be improved).
