Detailed Description

"Model of Explicit scheme with time integration algorithm. Finite difference model a numerical representation of the math equations

" U(n+1) = U(n) - lambda*{ F(i+1/2) - F(i-1/2)} + SourceTerms + Pressure Term The last equation can be put in an operator form as follow: U(n+1;j) = H(U(n); t) where "H" is called discretization operator.

Design Note: responsible to evaluate the following model: U(n+1) = U(n) -lambda*F - dt*S advance through time.

where F is the numerical flux at the interface (j+1/2), it is the derivative (F=F_i-F_i-1), S is the source term. Default stepping is the Euler integrator.

User can change the time stepping and flux algorithm.
