fullphysics

fullphysics refers to a computational approach in scientific and engineering simulations where all relevant physical phenomena are modeled simultaneously within a single framework. This contrasts with traditional methods that might discretize different physical processes and solve them sequentially or independently. The core idea behind fullphysics is to capture the complex interactions and couplings between various physical domains, such as fluid dynamics, solid mechanics, heat transfer, electromagnetics, and chemical reactions.

This integrated approach is particularly valuable when these phenomena are strongly interdependent and cannot be accurately represented in isolation. For instance, in a system where heat generated by mechanical deformation influences material properties and subsequently affects the deformation itself, a fullphysics simulation would model both aspects concurrently. This can lead to more accurate predictions and a deeper understanding of the overall system behavior.

Implementing fullphysics often requires sophisticated numerical algorithms and high-performance computing resources due to the increased complexity and computational demand. The development of robust solvers capable of handling diverse physical laws and their interconnections is crucial. Despite the challenges, the benefits of fullphysics simulations include improved accuracy, the ability to model novel phenomena, and the potential to optimize designs by considering all critical physical aspects from the outset. Applications span across numerous fields, including aerospace, automotive, biomedical engineering, and materials science.
