ZeroDivisionError when using forward Kirchoff operator with dynamic = True and engine="numba"

[arietu]

When I apply forward Kirchoff operator with dynamic =True and engine = "numba" an error appears at the "_matvec" method.

I forgot to mention that this happens when mode='byot' where I add my own trav and amp arrays.

and everything works fine when engine='numpy'

Hello @arietu, this is likely due to the fact that you provide some of the amplitudes with zero.

Without a full error report I cannot tell exactly but this is what I suspect. It may work fine with engine=numpy as numpy let’s you do a division by zero and returns inf (or nan) while numba raises an error

[arietu]

the problem was due to the following line of code: aperture = abs(sixisrcrec - rixisrcrec) / iz

where 'iz' can be zero sometimes.

Right I see. This issue was recently fixed as part of a larger PR (it is currently until review and will be merged soon :) )
