Constructs a general trapezoid.

Parameters:

• name (str) – name of the volume

• pDz (float, Constant, Quantity, Variable, Expression) – half length along z

• pTheta (float, Constant, Quantity, Variable, Expression) – polar angle of the line joining the centres of the faces at -/+pDz

• pPhi (float, Constant, Quantity, Variable, Expression) – azimuthal angle of the line joining the centres of the faces at -/+pDz

• pDy1 (float, Constant, Quantity, Variable, Expression) – half-length at -pDz

• pDx1 (float, Constant, Quantity, Variable, Expression) – half length along x of the side at y=-pDy1

• pDx2 (float, Constant, Quantity, Variable, Expression) – half length along x of the side at y=+pDy1

• pAlp1 (float, Constant, Quantity, Variable, Expression) – angle wrt the y axis from the centre of the side (lower endcap)

• pDy2 (float, Constant, Quantity, Variable, Expression) – half-length at +pDz

• pDx3 (float, Constant, Quantity, Variable, Expression) – half-length of the side at y=-pDy2 of the face at +pDz

• pDx4 (float, Constant, Quantity, Variable, Expression) – half-length of the side at y=+pDy2 of the face at +pDz

• pAlp2 (float, Constant, Quantity, Variable, Expression) – angle wrt the y axis from the centre of the side (upper endcap)
