Models and Mapping
==================

In SimPEG, the model represents the set of parameters that define our geology.
For many problems, the model is a vector containing one or more physical
property values for each cell in the mesh.
This method and additional methods for parameterizing models will be
demonstrated in the tutorials.

Simulations and inverse problems in SimPEG require the user to define a
mapping which goes from the model space to the vector space containing the
mesh. For different types of models, we will demonstrate how this mapping
is generated and applied.
