+## Using checkpoint generated by code of lower dimension
+The Toolkit allows for initializing higher dimensional calculations via checkpoint generated by lower-dimensional code, for example, 3D code can be initialized by checkpoints generated by 2D or 1D code.

 # Custom initialization of the solver
 The static codes can start the self-consistent process from arbitrary initial conditions. To activate this option user must specify in the input file:
