                       GrainSurface coreSurface)

Create an Hollow cylindrical propellant grain

Parameters:

propellant - propellant used (for default propellant see PropellantType)

outerDiameter - outer grain diameter in millimeter

coreDiameter - core grain diameter in millimeter

segmentLength - the length of a segment gran in millimeter. Example : if using 4 grains of 34mm each, segmentLength is 34.

numberOfSegment - the number of segment

outerSurface - outer surface is exposed to combustion or inhibited

endsSurface - end segments surface are exposed to combustion or inhibited

coreSurface - core surface is exposed to combustion or inhibited
