Greeting SIMPEG community,

My name is Michael Faran and I am very excited to use the software.

I am attempting to solve a certain problem I am currently facing, related to a FDEM 2D problem, similar to the link.

I want to show that SimPeg has potential for simulating forward EM fields correctly. The geometry of interest is a grazing angle Hz propagating along a boundary between air and homogenous half-space of water. I consider two horizontal loops of AC current above homogenous half-space of water. One is Tx and the other is Rx. I am trying to get the solution of decay by 1/ R^5 very far from the Tx Coil, as appearing in the paper

Nevertheless, when I activate my code I get a 1/ R^3 signal very far from the TX coil, and I do not understand what I am doing wrong.

I used a total magnetic field Tx and Rx FDEM simulation instead of secondary magnetic field, but it does not seem to alter the result

I wanted to attach my .py code, but I couldnâ€™t.

Did anyone encountered this problem before?

Any ideas?

any help would be much appreciated,

Thanks,

Michael
