This paper conducts a comprehensive analysis of undulating and oscillatory movements in fish, utilizing numerical simulations to explore correlations among fin thrust and swimming speed. The study distinguishes itself through a unique approach by employing kinematic equations of motion control, specifically in oscillation and undulation, for computational fluid dynamics. Despite increasing energy loss with undulation, the study reveals a reduction in power demand with oscillation, underscoring its effectiveness in achieving desired speeds. The dynamics of undulating fins in aquatic and aerial locomotion remain insufficiently understood. The trade-off between more energy-consuming but highly propulsive movements or simpler and faster movements requires sophisticated design techniques to reduce volume. The geometry, developed using Rhino 6 software, incorporates precise fluid resistance calculations conducted with Ansys Fluent 19. Spanning flow velocities from 1 to 4 m/s were used for the simulation condition. Critical factors such as flexibility, viscosity, and shape change were meticulously examined for their impact on efficiency enhancement.

“…One of the most exciting research opportunities for the usage of 3D modeling is computational fluids dynamics (CFD) research and more generally, computer simulation (Fauci and Peskin, 1988;Fish and Lauder, 2017;Laforsch et al, 2012;Lauder, 2015). The use of CFD is widespread within the realm of mechanical engineering and animal locomotion and is viewed as a vital tool for understanding the consequences of variation in body shape on locomotor efficiency in a range of animals, primarily those that move in air or water, such as fish, marine mammals, and birds, among others (Cohen and Cleary 2010;Dong et al, 2020;Liu, 2002;Nakata et al, 2011;Ravi et al, 2020). It is also critical for better tag designs in biologging research, where the interplay between body shape and form factor of the tag is critical for the developing drag when the tagged animals move in air and water (Shorter et al, 2014;Vandenabeele et al, 2014).…”

The use of meshfree and particle methods in the field of bioengineering and biomechanics has significantly increased. This may be attributed to their unique abilities to overcome most of the inherent limitations of mesh-based methods in dealing with problems involving large deformation and complex geometry that are common in bioengineering and computational biomechanics in particular. This review article is intended to identify, highlight and summarize research works on topics that are of substantial interest in the field of computational biomechanics in which meshfree or particle methods have been employed for analysis, simulation or/and modeling of biological systems such as soft matters, cells, biological soft and hard tissues and organs. We also anticipate that this review will serve as a useful resource and guide to researchers who intend to extend their work into these research areas. This review article includes 333 references. Highlights  We present an up to date review of meshfree and particle methods, including their advantages and limitations.  We comprehensively discuss past and recent applications of meshfree and particle methods in bioengineering and biomechanics.  We identify research areas, directions, and opportunities for the application of meshfree and particle methods in bioengineering and biomechanics.
