Dear Ashish Kumar Singh,
I see nothing particularly wrong in your input. I cannot fully check your
problem because the fluence file you sent contains only 99 lines.
Probably you are just missing the tiny air volume, in which the
interaction probabilityy for photons is small.
I would suggest to score DOSE-EQ over the whole interior of your house
structure, for instance with a cartesian binning having 10cm wide in in
all directions.
This has the advantage of calculating dose on the basis of particle
fluence, instead of deoposited energy, which is much more efficient when
dealing with very low densities.
This will also give you an idea of the distribution of particle fluence
inside the "house"
You can also add flence usrbins, scoring pphotons otr ALL-PART, covering
your whole haose, to check that the particles are travelling where you
expect to travel.
Regards
Paola
