+### MAST-U
+The second example is a poloidal section through the MAST-U device, using the magnetic field given in the file `B.pts`.  The heat diffusion is again isotropic, favouring the magnetic field direction.
+
+For the boundary conditions, the core region is held at a high temperature `TCore`, and the outer region at a low temperature (300 and 0 respectively for these images).  Currently the domain does not have axial symmetry, so does not completely represent the true scenario.
