Finite Element Heat Transfer and Field Problems
Definition
Finite element heat transfer and field problems apply the finite element workflow to scalar or vector fields beyond structural displacement, including temperature, seepage, inviscid flow, torsion, acoustics, and viscous incompressible flow.
How It Works
The governing field equation and boundary conditions are written in a weak or weighted residual form, discretized over elements, assembled into a global system, and solved under steady-state, transient, linear, or nonlinear assumptions. The source treats heat transfer first, then general field problems, then viscous incompressible fluid flow and fluid-structure interaction.
A-First-Course-in-the-Finite-Element-Method adds an introductory transport path: heat conduction is derived from energy conservation and Fourier's law, then formulated in one, two, and three dimensions; mass transport and fluid flow are treated through analogous finite element equations.
Abaqus-Analysis-User-s-Guide-Volume-II adds production procedure coverage for heat transfer, coupled thermal-stress, adiabatic analysis, incompressible CFD, electromagnetic procedures, pore fluid diffusion and stress, mass diffusion, acoustic and shock analysis, Aqua loading, sequential coupling, and co-simulation.
Why It Matters
The chapter shows that finite element procedures are not limited to solid mechanics. Similar discretization and assembly patterns can solve different physical laws when the governing equations and boundary terms are formulated correctly.
