Detailed Description

Abstract base class for geometries.

This class encapsulates computational geometries in chombo-discharge. If you construct this object as-is, you will get a blank geometry. To include EBs one must set the electrodes and dielectrics. This is not a pure function, so you can set those objects directly from a ComputationalGeometry object. However, in almost all cases one will want to derive from ComputationalGeometry and create a parametrized geometry (that is what $DISCHARGE_HOME/Geometries is for!).

Member Function Documentation

◆ buildGasGeometry()

void ComputationalGeometry::buildGasGeometry	(	GeometryService *&	a_geoserver,
		const ProblemDomain	a_finestDomain,
		const RealVect	a_probLo,
		const Real	a_finestDx
	)

protected

Set up the geometry generation tool for the gas phase.

Parameters

[in,out]	a_geoserver	Geometry service object which is later used for making build the EB information.
[in]	a_finestDomain	Finest domain which will be used
[in]	a_probLo	Lower-left corner of simulation domain.
[in]	a_finestDx	Finest resolution which will be used.

◆ buildGeometries()

void ComputationalGeometry::buildGeometries	(	const ProblemDomain	a_finestDomain,
		const RealVect	a_probLo,
		const Real	a_finestDx,
		const int	a_nCellMax,
		const int	a_maxGhostEB,
		const int	a_maxCoarsen = `-1`
	)

virtual

Build geometries and the MFIndexSpace.

Parameters

[in]	a_finestDomain	Finest domain
[in]	a_probLo	Lower-left corner
[in]	a_finestDx	Finest grid resolution
[in]	a_nCellMax	Patch size
[in]	a_numEbGhost	Maximum number of EB ghosts that will be encountered.
[in]	a_maxCoarsen	Max coarsenings to run. If = -1 then coarsen all the way down.

This will build the gas and solid phase domain. The input is the finest-level stuff and you can control the division into boxes as well as the maximum number of coarsenings. The computed domain is (a_probLo, a_probLo + a_box*a_dx)

◆ buildSolidGeometry()

void ComputationalGeometry::buildSolidGeometry	(	GeometryService *&	a_geoserver,
		const ProblemDomain	a_finestDomain,
		const RealVect	a_probLo,
		const Real	a_finestDx
	)

protected

Parameters

[in,out]	a_geoserver	Geometry service object which is later used for making build the EB information.
[in]	a_finestDomain	Finest domain which will be used
[in]	a_probLo	Lower-left corner of simulation domain.
[in]	a_finestDx	Finest resolution which will be used.
