I want to evaluate 3d effects in 1d inversion in TDEM. In other words, I want to calculate a forward response for a general 3d model and then invert the modeled data in 1d.
To start somehow, I’ve tried to modify the TDEM exapmles found at the SimPEG webpage, e.g. the “EM: TDEM: 1D: Inversion with VTEM waveform” However, I’ve got completely lost during the inversion part.
I’ve created the tensor mesh and assigned conductivities. Plotting the slice suggests everything is fine up to now (line 66). Also the forward response is somehow calculated. However, I’m not able toi set up the inversion for 1d, I always ends up with dimension mismatch, but I’m not able to figure out, where is the problem. Might be it is connected with the dmisfit (line 109)?

Could someone help me, please? I’m completely lost.
P.S. By the way, how to attach a text file? Just images are allowed by the upload function…
