Issues with AMR:

[smarandeshmukh]

I have been unable to make raytracing work with simple AMR grids. I use the same example as in #203. I get a segmentation fault with the following:
#3 0x4A7E99 in __grid_geometry_specific_MOD_find_position_in_grid at grid_geometry_amr.f90:531 #4 0x4A7C26 in __grid_geometry_specific_MOD_find_cell_position at grid_geometry_amr.f90:559 #5 0x4A7CE2 in __grid_geometry_specific_MOD_find_cell at grid_geometry_amr.f90:550 #6 0x4A79FB in __grid_geometry_specific_MOD_place_in_cell at grid_geometry_amr.f90:565 #7 0x4D7F4B in __peeled_images_MOD_peeloff_photon at images_peeled.f90:152 #8 0x4EDF0D in __iteration_raytracing_MOD_do_raytracing at iter_raytracing.f90:121 #9 0x4EF18C in MAIN__ at main.f90:299
This happens after the normal imaging process has been completed. Has anybody else encountered something along these lines? A cursory glance suggests that Hyperion can't correctly identify in which cell the source resides in.

Thanks
