Member Function Documentation

merge2cells()

void dv_pos::merge2cells ( const int imrg, const double m1, const double m2, const bool LconstVolume = false )

virtual

dv_pos merge2cells function

Function presumes that the variable being merged is a quantity per unit mass. Merging conservatively: (rho*phi*dx)_merged = (rho*phi*dx)_1 + (rho*phi*dx)_2 Then solve for phi_merged.

NOTE: this should only be called when posf is correct.

Parameters

imrg	input: merge cells imrg and imrg+1
imrg	input: merge cells imrg and imrg+1
m1	input: mass in cell imrg
m2	input: mass in cell imrg
LconstVolume	input: (for posf, default is false)

setDvFromRegion()

void dv_pos::setDvFromRegion ( const int i1, const int i2 )

virtual

Set data array from region of domain.

Parameters

i1	input: index of starting cell of domn to build from
i2	input: index of ending cell of domn to build from See domain::setDomainFromRegion for additional details.

setVar()

void dv_pos::setVar ( const int ipt = -1 )

virtual

dv_pos setVar function

Parameters

ipt	input: optional point to compute at Sets the grid position from posf So, you should make sure posf is consistent with pos before calling.

NOTE: this should only be called when posf is correct.

splitCell()

void dv_pos::splitCell ( const int isplt, const int nsplt, const vector< double > & cellFaces )

virtual

dv_pos splitCell function

Parameters

isplt	input: index of cell to split
nsplt	input: number of cells to split cell into
cellFaces	input: original left edge, new interior faces, orig. right edge.

note, the number of cells is changed in the calling function, not here note, this is organized to be independent of whether we split posf before or after. (that is, we often compute pos1 as simply 0.5*(posf1+posf2), but not here.
