Input file generator for Chad Landis Phase Field code (finite element method) (study ferroelectric polarization domain morphology):

Input file: 
1. dbcs:                 boundary condition of fundamental degree of freedom
                         dbcsgenerator.py


2. fbcs (not necessary): external force boundary codition. 
                         displacement -> force
                         electro static potential -> charge
                         polarization -> microforce


3. elements:             8 nodeal indexes in one cube elements
                         elementsgen.py


4. nodes:                nodal index
                         nodesgen.py
                         
                        
Data analysis:
1. Energy:               Calculate thin film total free energy

2. BTO phase scan:       Scan BTO phase (pointwise, planewise)
