Continuum Mechanics refers to the branch of mechanics that studies the behavior of materials modeled as continuous mass rather than discrete particles. This skill encompasses the analysis of stress, strain, and deformation in solid and fluid materials under various forces and conditions. Knowledge of Continuum Mechanics is used to predict material responses in engineering applications, such as structural analysis, fluid dynamics, and material science, enabling the design and optimization of systems and structures.

Fluid Structure Interaction refers to the study of the interaction between fluids and solid structures, focusing on how the movement and forces of fluids affect the behavior of structures and vice versa. This skill encompasses the principles of fluid dynamics and structural mechanics, enabling the analysis and prediction of performance in various engineering applications. Knowledge of Fluid Structure Interaction is used in fields such as aerospace, civil engineering, and biomedical engineering to design safer and more efficient structures by understanding the effects of fluid forces on structural integrity and performance.

Multibody Dynamics is a specialized engineering discipline that deals with the analysis and simulation of the mechanical systems that involve the motion of multiple bodies or parts interacting with each other. It is used to study the movement and interactions of complex mechanical systems such as vehicles, robots, satellites, and machinery. The goal of multibody dynamics is to predict the behavior of these systems, including their motion, forces, and energies, in order to optimize their performance and design. It requires a deep understanding of mechanics, mathematics, and computer programming, as well as specialized software tools for simulation and analysis.

Multiphysics is a specialized field that involves the simultaneous study of multiple physical phenomena such as heat transfer, fluid flow, and electromagnetism in a single system or device. It requires expertise in different scientific disciplines, mathematics, and computer modeling tools to understand, simulate and analyze interactions between different physical variables. Multiphysics applications are found in many fields, including engineering, material science, bioengineering, and environmental sciences.

OpenFOAM is a free, open-source software for computational fluid dynamics (CFD) simulations. It provides a wide range of solvers, models and utilities for simulating complex fluid flows in various industries including aerospace, automotive, energy, and process engineering. OpenFOAM requires specialized knowledge in numerical methods, programming and CFD procedures to effectively use the software.
