Deriving Numerical Procedures of Heat and Moisture Transport Modelling - Computer Implementation
Original language description
Three types of equations must be solved during nonlinear coupled transport problems. There are constitutive equations (retention curves, material properties), transport equations (Fick's law, Darcy's law and Fourier's law) and continuity equations. Afterdiscretization of driving equations using finite elements method, we obtain system of non-symmetric and non-linear algebraic equations. It is convenient to extend numerical solution by Newton - Raphson method for non-linear system of equations, mainly if material properties have strong non-linear dependence. This fact dramatically increases solution time and requirements for computer hardware (CPU speed, size of RAM). The type of matrix storage and type of solution method is changing. The advantage ofparallel programming can be successfully exploited.
