Hi @Arsalan, thanks for your questions! I will try to give you a few pointers to code and examples.

1. I assume you are starting with `TensorMesh` meshes. These are the simplest from the user perspective for getting up and running. There are [some tutorials](http://discretize.simpeg.xyz/en/master/tutorials/mesh_generation/2_tensor_mesh.html#sphx-glr-tutorials-mesh-generation-2-tensor-mesh-py) available that discuss setting up meshes. For a 3D mesh,

2. I think @sgkang09 has a few examples. Are you looking to run a 1D simulation or a 3D one. If you are planning to start with 1D, I would recommend taking a look at [SimPEGEM1D](https://github.com/simpeg/simpegEM1D)

3. If you are using a `dbdt` receiver, then you can provide voltages. [This conversation on input data](https://simpeg.discourse.group/t/input-data-in-simpeg-em/50) is quite relevant here (and it sounds like you might be working with a similar survey setup to @jcbarreto!)

I hope this is a helpful starting point. I will circulate this post and see what other relevant examples we can point you to.
