# 5.1. Create Model¶

Here, the code blk3cell.exe is used to construct a magnetic susceptibility model on the tensor mesh provided. Files relevant to this part of the example are in the sub-folder create_model. Before running this example, you may want to do the following:

For our example, the input file used to create the susceptibility model is shown below (blk3cell.inp)

The resulting model shows a more susceptible block ($$\kappa$$ = 0.025 SI) inside a much less susceptible background ($$\kappa$$ = 0.0001 SI). The locations used to model the data are shown as well.
