Detailed Description

Example of an circular/spherical explosion for the MHD solver.

Parameters: a_smallPressure - Lower limit for pressure (returned) a_gamma - Gamma for polytropic, gamma-law gas a_pressure_jump - p/p_0 inside explosion at initial time a_density_jump - rho/rho_0 inside explosion at initial time a_p0 - background pressure outside explosion a_rho0 - background density outside explosion a_B_direction - direction of initial magnetic field a_B_magnitude - magnitude of initially constant magnetic field a_center - Center of the explosion a_size - Initial radius of the explosion a_velocity - Initial velocity of the system a_artvisc - Artificial viscosity coefficient

Null constructor.

ExplosionIBC::ExplosionIBC (  Real &  a_smallPressure,
const Real &  a_gamma,
const Real &  a_pressure_jump,
const Real &  a_density_jump,
const Real &  a_p0,
const Real &  a_rho0,

const Real &  a_B_magnitude,
const RealVect &  a_center,
const Real &  a_size,
const RealVect &  a_velocity,
const Real &  a_artvisc
) 
 

Constructor which defines parameters used by Fortran routines.

Parameters: a_smallPressure - Lower limit for pressure (returned) a_gamma - Gamma for polytropic, gamma-law gas a_pressure_jump - p/p_0 inside explosion at initial time a_density_jump - rho/rho_0 inside explosion at initial time a_p0 - background pressure outside explosion a_rho0 - background density outside explosion a_B_direction - direction of initial magnetic field a_B_magnitude - magnitude of initially constant magnetic field a_center - Center of the explosion a_size - Initial radius of the explosion a_velocity - Initial velocity of the system a_artvisc - Artificial viscosity coefficient

void ExplosionIBC::artViscBC (  FArrayBox &  a_F,
const FArrayBox &  a_U,
const FArrayBox &  a_divVel,
const int &  a_dir,
const Real &  a_time
)  [virtual]
 

Adjust boundary fluxes to account for artificial viscosity.

Implements PhysIBC.

void ExplosionIBC::initialize (  LevelData< FArrayBox > &  a_U  )  [virtual]
 

Set up initial conditions.

Implements PhysIBC.

PhysIBC* ExplosionIBC::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 ExplosionIBC::primBC (  FArrayBox &  a_WGdnv,
const FArrayBox &  a_Wextrap,
const FArrayBox &  a_W,
const int &  a_dir,
const Side::LoHiSide &  a_side,
const Real &  a_time
)  [virtual]
 

Set boundary primitive values.

Implements PhysIBC.

void ExplosionIBC::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 ExplosionIBC::setFortranCommon (  Real &  a_smallPressure,
const Real &  a_gamma,
const Real &  a_pressure_jump,
const Real &  a_density_jump,
const Real &  a_p0,
const Real &  a_rho0,
const int &  a_B_direction,
const Real &  a_B_magnitude,
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.
