Description: Quasi-static multimodal models are analytical approaches used to study complex systems where multiple modes of interaction are combined. These models assume that the conditions of the system remain nearly constant during the analysis process, allowing for the simplification of equations and facilitating problem-solving. In this context, ‘quasi-static’ implies that the variations in the system are slow enough that the system can be considered in equilibrium at each moment. This characteristic is fundamental for modeling phenomena involving multiple variables and modes of operation, such as in engineering, physics, and applied sciences. Quasi-static models enable researchers and professionals to perform more accurate simulations and predictions while reducing computational complexity. Furthermore, these models are particularly useful in situations where rapid changes can lead to nonlinear or unstable results, providing a valuable tool for the design and analysis of systems across various disciplines.
