These methods do not rely on further assumptions within the solution process since they base solely on the general formulation of the underlying equations.
In its numerical solution process, this engine would take control and would call the problem model subroutine iteratively, not returning to the calling template until its system problem was solved.
These methods start the solution process from a guessed distribution of the variable and perform successive updates until a converged solution is obtained.
Neutralization or ionomerization, can also be accomplished in two ways: the acid copolymer can be melt-mixed with a basic metal or neutralization can be achieved through solution processes.
