I am trying to model the behaviour of a reactor vessel when some
particles inside the container strike the inner wall using FINITE
ELEMENT MODELLING software.

I reproduced several random particles hitting the wall at different
times and position across the surface of the inside wall.

Now I would like to get rid of the TRANSFER FUNCTION of the container
from the random particles data using the deconvolution to extract only
the particle informations.

I apply an inpulse inside the vessel (the middle) and I acquire the
output on the outer surface.

THe PROBLEM: How can I deconvolve the spectra in a right way?
In fact the TRANSFER FUNCTION of the vessel changes according with the
position of the impact.

The tranfer function of the vessel will be completely different when
considering the position A or position B.
