AddFieldValue()

void F04FocusSolenoid::AddFieldValue ( const G4double  point[4], G4double  field[6]  ) const

virtual

AddFieldValue() adds the field for this solenoid into field[]. point[] is in global coordinates.

Reimplemented from F04SimpleSolenoid.

   G4ThreeVector global(point[0],point[1],point[2]);

   G4ThreeVector local = fGlobal2local.TransformPoint(global);

   if (IsOutside(local)) return;

   G4double length = ((F04SimpleSolenoid*)this)->GetLength();

   G4double Bz = (fB2-fB1) * std::abs(local.z())/(length/2.) + fB1;
