a Schematics of an immersed body in a fluid domain. \(\varOmega _f\) and \(\varOmega _s\) are the fluid and solid domain, and \(\varGamma _f\) and \(\varGamma _s\) are the boundary surfaces of the fluid and solid domains, respectively. b Illustration of the solid volume fraction \(\alpha \) within a finite volume grid cell
