public ExtrudedShapeGrain()

Method Details

getGrainEndSurface

public double getGrainEndSurface(double burnProgression)

Description copied from interface: GrainConfigutation

Compute the end grain surface during burn

Specified by:

getGrainEndSurface in interface GrainConfigutation

Parameters:

burnProgression - (0 to 1, 0 = before burn start ; 1 = grain completly burn)

Returns:

the end grain surface in mm^2

getGrainVolume

public double getGrainVolume(double burnProgression)

Description copied from interface: GrainConfigutation

Compute the grain volume during burn

Specified by:

getGrainVolume in interface GrainConfigutation

Parameters:

burnProgression - (0 to 1, 0 = before burn start ; 1 = grain completly burn)

Returns:

the grain volume in mm^3

getBurningArea

public double getBurningArea(double burnProgression)

Description copied from interface: GrainConfigutation

Compute the burning area during burn

Specified by:

getBurningArea in interface GrainConfigutation

Parameters:

burnProgression - (0 to 1, 0 = before burn start ; 1 = grain completly burn)

Returns:

the burning area mm^2

getXincp

public double getXincp(int numberOfPoints)

Description copied from interface: GrainConfigutation

This method should return the length that will be remove in each computation iteration ex : for hollow cylinder grain this will be : initial web thickness / numberOfPoints

Specified by:

getXincp in interface GrainConfigutation

Parameters:

numberOfPoints - the number of iteration during the computation

Returns:

xincp (cf. SRM_2014.xls)

webThickness

public double webThickness()

getNumberOfSegments

public abstract int getNumberOfSegments()
