A cartesian mesh is a mesh that represents structured mesh whose nodes are arranged along axes of trihedron.
To instantiate an object of this type, only n arrays are needed.
In this type of mesh space dimension and mesh dimension are equals and the value is n ( with n in [1,2,3] ).
The n arrays will have only one component and the values contained in these arrays will be ascendently sorted.
The class that incarnates the described concept is : MEDCoupling::MEDCouplingCMesh.
Let's present an example of a 2D cartesian mesh.
