Unbeaching kernel having issues when using 2D simulations instead of 3D

[martoconnh]

It was caused due to the fact that the unbeaching kernel activates by default when the windage kernel is used. The problem seems to be in kernels.py, on line 552:

(vel_u, vel_v, vel_w) = fieldset.UVW[time, particle.depth + particle_ddepth, particle.lat + particle_dlat, particle.lon + particle_dlon] # noqa

If the fieldset is not defined in 3D, it does not have the attribute "UVW", it has "UV" instead, causing the simulation to crash. Hope this helps!

Thanks for raising this in our discussion @martoconnh. This is something I'll pickup soon to fix!
