Bellhop run failing on Linux

abhiram-gorla commented 3 years ago

Screenshot from 2020-09-30 17-52-53 ValueError: could not convert string to float: ' 0.00000000 5.00000000 \n' I am using ubuntu18.04 python3.8 i have been trying to run bellhop model for under water channel simulation . I have install the at_Linux.taz.gz for acoustic toolbox please help

Please run the compute_eigenrays() call with a debug=True argument. That should retain the env and prt files in the tmp folder for the bellhop call. Post those here to see what might be the problem.

Seems that the Bellhop run was successful. That should have generated a .ray file. Could you upload that as well please?

abhiram-gorla commented 3 years ago

file.zip zip file for .ray .prt .env files please check

mchitre commented 3 years ago

If you look at the prt file, you'll find the reason for the failure:

 *** WARNING ***
 Generated by program or subroutine: TraceRay2D
 Insufficient storage for ray trajectory

It seems that Bellhop is unable to store all the ray trace for the number of beams you have specified.

@abhiram-gorla : Strange, I ran your files, and works perfectly fine on my machine. Attached are the results.
