Initial Conditions: Initial conditions specify the values of variables at the starting point of a physical process or equation.
Periodic Boundary Conditions: Periodic boundary conditions assume that a physical system repeats itself periodically, allowing it to be studied within a finite region.
Dirichlet Boundary Conditions: Dirichlet boundary conditions specify fixed values for variables at the boundaries of a physical system.
