Description
Proper Orthogonal Decomposition Methods for Partial Differential Equations evaluates the potential applications of POD reduced-order numerical methods in increasing computational efficiency, decreasing calculating load and alleviating the accumulation of truncation error in the computational process.
Introduces the foundations of finite-differences, finite-elements and finite-volume-elements. Models of time-dependent PDEs are presented, with detailed numerical procedures, implementation and error analysis. Output numerical data are plotted in graphics and compared using standard traditional methods.
These models contain parabolic, hyperbolic and nonlinear systems of PDEs, suitable for the user to learn and adapt methods to their own R&D problems.
Key Features
·Explains ways to reduce order for PDEs by means of the POD method so that reduced-order models
have few unknowns
·Helps readers speed up computation and reduce computation load and memory requirements while
numerically capturing system characteristics
·Enables readers to apply and adapt the methods to solve similar problems for PDEs of hyperbolic,
parabolic and nonlinear types
Readership
Graduate students and researchers in mathematically intensive environments who perform large scale
computations.
